Turned into an equation:
4 + sqrt(6x) = 16
Subtract 4 from both sides:
sqrt(6x) = 12
Square both sides:
6x = 144
Divide both sides by 6:
x = 144 / 6
x = 24
The answer is 24

Let x be the required number.
According to the statement,
v6x+4 =16 [v means "square root of"]
=> v6x +4 - 4 =16 - 4
=> v6x = 12
Squarring on both sides,
(v6x)^2 = 12^2
=>6x = 144
=>6x/6 = 144/6
=>x = 24
verifying the value, we get
v6.24 +4 =v144+4 =12+4 =16 [This verifies the statement]
So, the required number is 24.

let x be the number be x
so, 4+√6x=16
√6x=16-4
(√6x)2 =(12)2
36x2 =144
x2=144/36
x2=4
so, x = +- √ 4
x =+- 2
So, the required number is 2(neglecting negative value)

24
16 - 4 = 12
12 = square root of 144
144/6 = 24

It is simple. You must to make an equation according to the question.
Let, the number is x.
So, the equation will be.....
4 + sqrt(6x) = 16
or, sqrt(6x) = 12
or, 6x = 144
or, x = 24
So, the number will be 24.

This can be translated to:
(√6x)+4=16
√6x=12
Square both sides:
(√6x)²=12²
6x=144
x=24
The number is 24.
