Question

Negative exponents in denominators can be evaluated using StartFraction 1 Over b Superscript negative and EndFraction nbsp equals​_______,not equals 0.

Answer 1

b Superscript positive

Explanation:

Negative exponents in the denominators can be evaluated by moving the function from the denominator to the numerator and changing the power from negative to the positive.

We have

1/b⁻² = b²

Moving the function with a power from denominator to numerator or from numerator to denominator changes the sign of the power. It is not equal to zero.

This is the property of exponents.
