Question

how do i get the answer for

1/2 * sqrt(128) * sqrt(50)

Answer 1

first step is to simplify sqrt(128)
128 = 64x2 so sqrt(64x2) = 8sqrt2

Answer 2

can you see how I got that?

Answer 3

ya, sry, was doin other problems
go on

Answer 4

so now we have 1/2*8*sqrt(2)*sqrt(50) = 4*sqrt(2)*sqrt(50)
now we just combine the square roots

Answer 5

sqrt(2)*sqrt(50) = what do you think?

Answer 6

sqrt(2*50)=sqrt(100) = 10
then 4*10 = 40
40 = 1/2 * sqrt(128)*sqrt(50)

Answer 7

thx, that clears up alot

Answer 8

that's it! well done
