Final answer:
To simplify b^2/b^4, subtract the exponent of the denominator from the exponent of the numerator, resulting in b^-2.
Step-by-step explanation:
To simplify the expression b2 ∕ b-4, we use the laws of exponents that state when dividing like bases, the exponents should be subtracted.
In this case, you subtract the exponent of the denominator from the exponent of the numerator:
b2 ∕ b-4 = b(2-4) = b-2
The result is b-2, which is b raised to the power of negative two.
