ANSWER

Step-by-step explanation
We are given the expression:

Since each of the terms have the same base (-6.1), we will simplify this by applying the law of indices.
When two terms have the same base but different powers:
=> If they are multiplying one another, we add the powers;
=> If one divides the other, subtract the power of the denominator from the numerator.
That is:

That is the simplified expression.
