Question

An expression is shown below if this expression is equivalent to 60, what must be the value of a? A.) 3 B.) 4 C.) 9 D.)16

Answer 1

Option (A)

Explanation:

Given expression is,

`5√(48a)=60`

Squaring on both the sides of the equation,

`(5√(48a))^2=(60)^2`

25(48a) = 3600

1200a = 3600

By dividing the equation by 1200,

a =
`(3600)/(1200)`

a = 3

Therefore, Option (A) will be the answer.
