Answer:

Note: Any number or variable(unknown) raised to the index or power zero (0)* is equal to one (1)*.

3. Solution

Given: x = 2 and y = 5

-4x^-2 + 3y^0

by substituting the values of x and y,

> -4(2)^-2 + 3(5)^0

> -4/(2)^2 + 3(5)^0

> -4/4 + 3(1)*

> -1 + 3 = 2

4. Solution

Given: x = 2 and y = 5

2x^0y^-2

by substituting the values of x and y

> 2(2)^0(5)^-2

>2(2)^0×1/(5)^2

>2(1)×1/25

>2×1/25
