Answer 2

`x = 9\ or\ x = 1`

Explanation:

Given

`x = 5 + √(16)`

Required

Find the value of x

`x = 5 + √(16)`

We start by taking the square root of 16; Square root of 16 is +4 or -4; So, we have:-

`x = 5 \±4`

The expression above can be split into two; This is as follows

`x = 5 + 4\ or\ x = 5 - 4`

`x = 9\ or\ x = 1`

Hence, the solution to
`x = 5 + √(16)` is B. 1 and C. 9
