Answer:
[tex]\frac{1}{b^2}[/tex]
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:
[tex]a^-1 = \frac{1}{a^1}[/tex]
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:
[tex]b^-2 = \frac{1}{b^2}[/tex]
