Question

good evening! I really need help in simplifying the radical 20a^2b

Answer 1

Is there a square root over that whole thing?

Answer 2

yes

Answer 3

\[2a*\sqrt(5b)\]

Answer 4

Under the square root, just simplify everything you have.

so 2 x 2 x 5 x a x a x b

You can take out a 2 because you have 2 of them, and you can take out an a because you have 2 of them.

2a root 5b

Answer 5

ok thank you! I had 2sqr5ab
