Question

Simplify:
√144a^2b^4

A) 12ab
B) 12a^2b^4
C) 12ab^2
D) 12b√a

Answer 1

Option C

Explanation:

`\sqrt{144 {a}^(2) {b}^(4) }`can be written as
`\sqrt{144 * {a}^(2) * {b}^(4) }`

`= > √(144) * \sqrt{( {a}^(2)) } * \sqrt{( {b}^(4)) }`

`= > 12 * {a}^{ (2)/(2) } * {b}^{ (4)/(2) }`

`= > 12a {b}^(2)`
