Evaluate the expression { - 4}^(2)

Question

Evaluate the expression
`{ - 4}^(2)`

Answer 1

Step 1: Let's evaluate the following expression

`(-4)^2`

Step 2: Solve the exponent expression:

`(-4)^2\text{ = -4 }\ast\text{ - 4 = 16}`

The correct answer is 16.

For the second case, we apply the same principle:

`-5^2\ast4\text{ = -5}\ast\text{ -5 }\cdot\text{ 4 = 25 }\ast4\text{ = 100}`
