This is due to radical to exponent change property which is

We  can consider some examples as below;

Hence, the square root of a number is defined to be equal to that number to the power.

Or we sometimes solve square root by taking the power as

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.
