Question

Need help !!!!!!!! Please !!!!!!!

Answer 1

Explanation:

A = 4 and B = 5

Explanation

Group the same prime factors into pairs

√(2 x 2) x (2 x 2) x 5

Rewrite each pair in exponent form

√2
`\sqrt{2^(2) x 2^(2) x 5`

use the
`\sqrt{2^(2) } = x` rule

(2 x 2)
`√(5)`

simplify

4√5

Answer 2

a = 4

b = 5

Explanation:

We are given square root 80
`(√(80) )` and we are to write it in the form
`\sqrt[a]{b}` and figure out what values are a and b.

First of all, we would find the factors of 80 which, preferably are a square of a number, and when multiplied give a product of 80, which are:

`√(16)` ×
`√(5)`

Since
`√(16)` can further be squared so we can write it as:

`√(80)` =
`4√(5)`
