What do you need help with?

isaidavila · Answer

A)
(√96/√6)-(√54/√6)
√(96/6)-√(54/6)
√16-√9= 4-3=1

superfly123 · Answer

@isaidavila dont we factor ou 96 then divide by 6 from there?

isaidavila · Answer

Is another way to do it

isaidavila · Answer

But do you understan D what I did?

greatlife44 · Answer

Excellent, check out how I did the problem. we want to simplify the radicals as much as possible by finding a number that we can take the square root of and get an integer i.e. whole number. 

$$\frac{ \sqrt{96}-\sqrt{54} }{ \sqrt{6} }  $$

we must simplify this right? check this out


$$\frac{ \sqrt{16}*\sqrt{6}-\sqrt{9}*\sqrt{6} }{ \sqrt{6} }$$

$$\frac{ 4\sqrt{6}-3\sqrt{6} }{ \sqrt{6} } = \frac{ \sqrt{6}(4-3) }{ \sqrt{6} } = 1$$

jhonyy9 · Answer

so for what you wan help from these ?

superfly123 · Answer

from 22 and down

jhonyy9 · Answer

ok

do you know how multiplie radicals ?

superfly123 · Answer

yes

jhonyy9 · Answer

there are squarroot multiplied squarroot - so how will be ?
for example 
sqrt(a) *sqrt(b) = ?

superfly123 · Answer

You multiply the radicands then simpify

superfly123 · Answer

for the first answer it should be 4 radical 2 minus 3 not 1

jhonyy9 · Answer

do you think it about your exercise 22 - first exercise ?

superfly123 · Answer

for exercise 21 shouldn't the answer be 4 radical 2 minus 3

jhonyy9 · Answer

you have said me exercise 22 - no ?

superfly123 · Answer

i did but im asking you for 21 also

jhonyy9 · Answer

sqrt96  - sqrt54
--------------- = ----------------
   sqrt6 

how you solve it ?

superfly123 · Answer

Sorry the answer to 21 is correct i messed up , okay anyway exercise 22

jhonyy9 · Answer

sqrt96 = sqrt(6*16) = 4sqrt6
sqrt54 = sqrt(9*6) = 3sqrt6

4sqrt6 -3sqrt6       sqrt6*(4-3)
-------------- = ----------- = (4-3) = 1
     sqrt6                       sqrt6

have you got it same ?

superfly123 · Answer

Sorry the answer to 21 is correct i messed up , okay anyway exercise 22

superfly123 · Answer

yes

jhonyy9 · Answer
