\left( 3sqrt{10+4} \right)\left( 4sqrt{10-5} \right)
\[\left( 3\sqrt{10+4} \right)\left( 4\sqrt{10-5} \right)\] simplify in radical expression.
3*4=12 10+4=14 10-5=5 14(5)=70 \[12\sqrt{70}\]
I tried that answer, not the right answer.
it is the right answer
are you sure you type the question in correctly?
yes i am sure.
you are entering this into like a online quiz?
it has to simplified into radical form.
No, it's online hw.
It's the only one I can't get.
Would you like me to show you the practice question? and give you the answer?
you can if you want, but the above cannot be simplfied anymore since 70=2*5*7 there are no perfect squares in 70
\[\left( 2\sqrt{6+3} \right) \left( 3\sqrt{6-4} \right)\]
2(3)=6 6+3=9 6-4=2 6(3)sqrt(2) =18sqrt(2)
answer is 24+\[24+\sqrt{6}\]
Haha that's the answer it's giving me.
24+sqrt(6)?
Lol yea
so this is multiplication right? not addition or subtraction or division? it is definitely multplication, right?
multiplication for sure.
ask your teachers. these solutions don't make sense
there has to be a mistake or something
It's annoying me. I always get 100% on the hw. Except for this one.
It's due by midnight
you have class tomorrow?
does it show you how to work the problem, jason?
if it does, we can try to follow the logic of the problem they did and see if we can get the answer they are looking for even though it will not be correct
yea, but with weird examples that don't relate to it.
Hold on, lemme get that for you.
\[\left( \sqrt{5} +\sqrt{2}\right) \left( \sqrt{2} +3\right)\]
sqrt(5)sqrt(2)+sqrt(5)*3+sqrt(5)sqrt(2)+sqrt(2)3 =sqrt(10)+3sqrt(5)+sqrt(10)+2sqrt(2) =2sqrt(10)+3sqrt(5)+2sqrt(2)
answer is: \[\sqrt{10} +3\sqrt{5} + 2 + 3\sqrt{2}\]
yes i made a mistke up there one sec
sqrt(5)sqrt(2)+sqrt(5)3+sqrt(2)sqrt(2)+3sqrt(2) =sqrt(10)+3sqrt(5)+3sqrt(2)+2
so maybe our problem was suppose to look like this
What seems to be the problem then? :/
On that practice question, I don't get how they got 24 +(sqrt)6
ok lets pretend the problem was 3(sqrt(10)+4)2(sqrt(10)-5) 6(sqrt(10)+4)(sqrt(10)-5) 6(10-5sqrt(10)+4sqrt(10)-20) 60-sqrt(10)-20 40-sqrt(10 so this doesn't work
so what did it say we are suppose to get?
blank + (sqrt) blank
ok let's look at that second one and see if we can get they got by making a problem sortof like but in the form of the example you gave
the answer to that second one was 24+(sqrt)6
omg i figured out the problem they meant
....? :]
so they have (2sqrt(6)+3)(3sqrt(6)-4)=24+sqrt(6)
yea, how did you get that?
okay try to entrt 100+srt(10)
OMG!
Thank you. Please elaborate?
lol this is the problem they meant: (3sqrt(10)+4)(4sqrt(10)-5)
ohhhhh my god. really? I didn't even see that. I'm sorry.
how could you see it when it was written wrong or in the homework wrong
you should totally tell your teacher of this mistake
Thank you so much for the help, and I will do that. I have a quiz tmrw.
do you understand how i got the answers? i don't expect you to understand how i was able to make the problem correct lol
