Did I simplify these sqareroot problems right??? I sure hope so!
1. sqrt 7 8 sqrt 18/sqrt 2= I got 3sqrt 7
2. sqrt 10 8 sqrt16/sqrt5 = I got 4sqrt2
And the last one38sqrt 8/64= I got 3sqrt3/4

Re: Did I simplify these sqareroot problems right??? I sure hope so!
First. In 1. Do you mean sqrt(7) 8 sqrt(18)/sqrt(2) ??? In this case, I got sqrt(7) * 8*3 or 24 sqrt(7). I think you forgot the 8 coefficient in front of the radical.
Just remember these are the rules. sqrt(m) * sqrt (n) = sqrt (mn). Also sqrt (5/3) = sqrt (5)/ sqrt(3) also you can always multiply the numerator and denominator of a fraction by the same quanity without changing the value.
A logarithm is just a misspelled algorithm.

(1) √ 7*8*√ 18/√ 2 = 24*√ 7
(2) √ 10*8*√16/√5= 32*√2

No my 8 should be * for the multiplication sign??? It's been a long night of checking over homework with lots of english to go??? Sorry
1 should be the square root of 7 times(*) the square rot of 18 over the square root of 2?
2. the square root of 10 times(*) the square root of 16 all over(divided by) the square root of 5
Sorry for the mix up

So you are right mom on 1 and 2 because they got exactly 8 times your answers!
But your 3rd last one: 38sqrt 8/64= You said you got 3sqrt3/4, please explain youself.
