Question

Evaluate a^2b^2? when a = 5 and b = 3.

Answer 1

`D) 7`

Explanation:

`a^(2) -2b^(2)`

`a=5`

`b=3`

`\left(5\right)^2-2\left(3\right)^2`

Calculate 5 to the power of 2 and get 25:-

`25-2* 3^(2)`

Calculate 3 to the power of 2 to get 9 and then multiply 2 and 9 to get 18:-

`25-18`

`=7`
