Question

when we add in powers and roots then it will change into ?​

Answer 1

If you have a power inside and a power outside of a bracket you multiply the powers. A negative power means “one over” so everything is sent to the bottom of a fraction. A fractional power means a root. The bottom of the fraction tells you which root to take and the top tells you which power.
