We are given the expression:
Let us evaluate the expression step by step:
Step 1:
Power of a power: In this rule we multiply the powers 4 and (-5) in the numerator.
Step 2:
Quotient of power: Here we will subtract the power of denominator from numerator.
Step 3:
Negative exponent: Here we take reciprocal of what we got in step (2) , that will make the power positive.
Answer: We will use three rules as shown above .
