When a=−2 and b=5, the expression (ab)^2evaluates to 100.
This means that the product of a and b is first calculated, and then the result is squared to obtain the final value of 100.
To evaluate the expression (ab)^2 for a=−2 and b=5, we substitute these values into the expression and perform the necessary calculations.
The expression (ab)^2 means that we first find the product of a and b and then square the result.
Let's break down the steps:
Substitute
a=−2 and b=5 into the expression: (ab)^2 =(−2×5)^2
Calculate the product inside the parentheses:
(−2×5)=−10
Square the result:
(−10)^2 =100
Therefore, (ab)^2 with a=−2 and b=5 is equal to 100.
Therefore, when a=−2 and b=5, the expression (ab)^2 evaluates to 100.
This means that the product of a and b is first calculated, and then the result is squared to obtain the final value of 100.
