Which expression is equivalent to b^-2

Step-by-step explanation:

Use the laws of exponents to find an equivalent value of b^-2.

The negative law of exponents states that a number with a negative exponents is equal to the reciprocal of that number to the positive exponent.

Basically:

Using this law, you can then simplify b^-2. The reciprocal of b^-2 is 1/b^-2, and by the negative law of exponents, b^-2 changes to a positive exponent:
