Exercise 31 Page 53

Note that in this case, there are no parentheses surrounding the negative.

- 36

Practice makes perfect
The expression - 6^2, or - 6 to the second power, can be written as minus the product of two 6 terms. Note that in this case, there are no parentheses surrounding the negative. - a^n ⇔ -1(a^n)This means that we should evaluate as though parentheses surround the exponent and multiply the result by -1.
- 6^2
- 6* 6
- (6* 6)
- 36
We can also multiply this using a calculator!
