Question

Three added to the square root of the product of nine and a number is equal to six. Find the number.

Answer 1

3 + sq rt (9x) =6

sq rt(9x) = 3

9x = 9

x = 1

Answer 2

3 + the square root of 9x = 6

Minus 3 from both sides.

Now you have the square root of 9x = 3

Now square both sides.

You have 9x = 9

Divide both sides by 9.

The answer is x = 1.
