Question

4. Explain the difference between (-5)2 and
- 5²

Answer 1

Answer:

The square of a negative number is a positive number as 2 negatives cancel when multiplied.

• (-5)² = (-5)*(-5) = 25

In this case the negative sign stays as is because it is not affected by a square.

• - 5² = - (5)*(5) = -25
