Question 17500
We start off with (-2/X) .
This we raise to the Fifth power.
(-2/X)^5 .Taking the 5 inside the bracket we get ((-2)^5/X^5)since both numerator and denominator have to be raised to the power. So we finally get (-32/X^5)

Raising to any power essentially means multiplying that number by itself that many times. In this case (-2/X) x (-2/X)x(-2/X) x (-2/X) x (-2/X) From this you can see that we get (-32/X^5)
