The equivalent of the expression
4^(-2) * 7^(-2) are (b) and (c)

How to determine the equivalent of the expression

From the question, we have the following parameters that can be used in our computation:


4^(-2) * 7^(-2)

Applying the law of indices, we have


4^(-2) * 7^(-2) = (1)/(4^2) * (1)/(7^2)

Evaluate


4^(-2) * 7^(-2) = (7^(-2))/(4^2)

Lastly, we have


4^(-2) * 7^(-2) = (1)/(28^2)

Hence, the equivalent of the expression are (b) and (c)
