Evaluate b2c-1 for b = 8 and c = -4. -16 1/16 16 256

 The correct option is (B) -16.

Step-by-step explanation:  We are given to evaluate the value of the following expression for b = 8 and c = -4 :

To find the value of expression (i), we need to substitute the values of b and c in equation (i).

We will be using the following property of exponents :

Therefore, from equation (i), we get

Thus, option (B) is correct.
