is the correct answer

Answer 2

Oh okay, Um thank you but maybe I wrote that down wrong because these are the only answer choices they gave me.

Answer 3

yeah the answer choices dont really make sence but this is how you solve it a(b+c)=ab+ac √2(3 √2+ √18)=(2x3√2) + (2x18)= 6√2+36

square root of 2( ³ square root of 2 + square root of 18 : This is the best way I can explain it

Answer 12

Answer 13

and not the cube root of two

Answer 14

that 3 looks like an index its so small

Answer 15

Oh, I'm so sorry!! I guess so its kind of hard to understand its off of Florida virtual school they don't give very much of an explanation! But it's the cubed root of two squared + square root of 18 unless I'm misinterpreting it and it is 3 times the square root of 2
