Whats the question?
OpenStudy (anonymous):
um
jhonyy9 (jhonyy9):
i m here
OpenStudy (anonymous):
\[3+\sqrt{x+19}-\sqrt{2} when x=6\]
jhonyy9 (jhonyy9):
so
3 + sqrt(x+19) -sqrt2 = ? for x=6 --- yes ?

OpenStudy (anonymous):
yes
jhonyy9 (jhonyy9):
substittute the 6 in place of x inside sqrt
OpenStudy (anonymous):
can u show me how to do it the hole thing
jhonyy9 (jhonyy9):
yes but you need cooperate and make what i have said to you - ok. ?
OpenStudy (anonymous):
ok

jhonyy9 (jhonyy9):
sqrt(x+19) = ? when x=6
OpenStudy (anonymous):
25
jhonyy9 (jhonyy9):
yes nice so sqrt25 = ?
OpenStudy (anonymous):
5
jhonyy9 (jhonyy9):
exactly

OpenStudy (anonymous):
then what
jhonyy9 (jhonyy9):
so use this result above in your exercise - can using it there ?
OpenStudy (anonymous):
so
3+\[\sqrt{5}-2\]
jhonyy9 (jhonyy9):
3 + sqrt(x+19) -sqrt2 = ? for x=6 --- yes ?
in place of sqrt(x+19) you can writing 5 - yes ?
OpenStudy (anonymous):
yea

jhonyy9 (jhonyy9):
why you have wrote there sqrt5 ?
jhonyy9 (jhonyy9):
this is just 5 without sqrt
OpenStudy (anonymous):
ook
OpenStudy (anonymous):
then what
solve
jhonyy9 (jhonyy9):
how will be than your equation now ?

OpenStudy (anonymous):
3+5-2
OpenStudy (anonymous):
the answer is 6 right
jhonyy9 (jhonyy9):
3+5 -sqrt2 = ?
sqrt2 how you eliminate ?
OpenStudy (anonymous):
idk um
jhonyy9 (jhonyy9):
sqrt2 is different term than 3 and 5 so you not can doing with nothing just assum 3 with 5 and what will get ?

8
jhonyy9 (jhonyy9):
3+5 = ?
jhonyy9 (jhonyy9):
yes so rewrite your equation how is now ?
OpenStudy (anonymous):
\[8-\sqrt{2}\]
jhonyy9 (jhonyy9):
make it equal zero and assum to both sides sqrt2 so what will get ?

OpenStudy (anonymous):
idk what u are saying can u show me
jhonyy9 (jhonyy9):
8-sqrt2 +sqrt2=0+sqrt2 - do you understand it now ?
OpenStudy (anonymous):
ok kind of
jhonyy9 (jhonyy9):
so than make the calculi
OpenStudy (anonymous):
i am still confeused

jhonyy9 (jhonyy9):
-sqrt2 +sqrt2 = ?
and
0 + sqrt2 = ?
OpenStudy (anonymous):
how would i solve that
jhonyy9 (jhonyy9):
- 1 +1 = ?
OpenStudy (anonymous):
1
OpenStudy (anonymous):
right

jhonyy9 (jhonyy9):
no
OpenStudy (anonymous):
o
jhonyy9 (jhonyy9):
yes zero
OpenStudy (anonymous):
ok then what
jhonyy9 (jhonyy9):
so in the left side what will remain there ?

OpenStudy (anonymous):
2
OpenStudy (anonymous):
no 8
jhonyy9 (jhonyy9):
8-sqrt2 +sqrt2=0+sqrt2 - do you understand it now ?
yes 8 and on the right side ?
OpenStudy (anonymous):
3
jhonyy9 (jhonyy9):
what is this 3 ?
Join the QuestionCove community and study together with friends!
Sign Up
jhonyy9 (jhonyy9):
on the right side there are 0+sqt2
OpenStudy (anonymous):
there are 2 answers
OpenStudy (anonymous):
there is
OpenStudy (anonymous):
\[8\sqrt{3}\]
OpenStudy (anonymous):
and

OpenStudy (anonymous):
\[8-2\sqrt{3}\]
jhonyy9 (jhonyy9):
please answer my question
OpenStudy (anonymous):
yea
jhonyy9 (jhonyy9):
so on the left side will get 8 and on the right side what will remain there ?
there are 0+sqrt2
OpenStudy (anonymous):
yea and
Join the QuestionCove community and study together with friends!
Sign Up
OpenStudy (anonymous):
so then what
jhonyy9 (jhonyy9):
ok sorry i have checked it above newly and you have got the right answer there above
8-sqrt2 will be
ok. ?
OpenStudy (anonymous):
ok but that answeris not there
jhonyy9 (jhonyy9):
because you need just to calculi the value of this equation for x=6
OpenStudy (anonymous):
3 and 2

jhonyy9 (jhonyy9):
so this mean that your exercise not is just what you have wrote there above - how is the text exactly ?
OpenStudy (anonymous):
u mean theanswer
jhonyy9 (jhonyy9):
3+sqrt(x+19) −√2 when x=6 you have wrote there above this
jhonyy9 (jhonyy9):
so for x=6 you have got
this equal 8-sqrt2
yes ?
OpenStudy (anonymous):
so would the answer be

Sign Up
jhonyy9 (jhonyy9):
yes that s all
OpenStudy (anonymous):
\[8-2\sqrt{3}\]
jhonyy9 (jhonyy9):
nojust 8-sqrt2
how you get this 2sqrt3 ?
jhonyy9 (jhonyy9):
are you here again ?
OpenStudy (anonymous):
its a answer
Join the QuestionCove community and study together with friends!
Sign Up
jhonyy9 (jhonyy9):
indifferent you have got 8-sqrt2
this is the right answer sure
jhonyy9 (jhonyy9):
ok. ?
jhonyy9 (jhonyy9):
so good luck
was my pleasure
bye
OpenStudy (anonymous):
ok what was the answer
OpenStudy (anonymous):
thats not there
