How about this one can you help me out on it??

5*square root of 4 + 10*square root of 4

wha

t

That would be 15*(sqrt4)

You know what the square root of 4 is. So, you can simplify it some more.

hes wrong answer 8

ally, settle down. The answer is obviously 30. Surely you can verify that with your calculator.

Ally is NOT correct.

sqroot(4)=2

5*sqroot(4)+10*sqroot(4)=5*2+10*2
=10+20=30

5*sqroot(4)+10*sqroot(4)=15*sqroot(4)=

15*2=30
