Answer:
D
Step-by-step explanation:
A square has four 90° angles. So:
15x-30=90 add 30 to both sides
15x=120 divide both sides by 15
x=8°
In order to rewrite an expression in radical form using exponents, we must consider the power of the root (is the radical the typical square root, cubed root, etc) and the value of any exponents contained in the radical.
Using this information, we will make the power of the radical the denominator of our exponent, and whatever exponent is contained in the radical will become the numerator.
Example:
√(x³) = square root of x³ = x^(3/2)
