Exercise 97 Page 52

To determine this power, it may be helpful to rewrite the term as a product instead. This will help us determine whether the result of the exponent is positive or negative.

(- 1.2)^2

PowToProdTwoFac

a^2=a* a

(- 1.2)*(- 1.2)

By rewriting the term as this expression, we can see that we will be multiplying two negative numbers. Therefore, the product will be positive.

(- 1.2)*(- 1.2)

MultNegNegTwoPar

(- a)(- b)=a* b

1.2* 1.2
