Which shows the following expression after the negative exponents have been eliminated? the fraction with numerator A cubed b to the negative 2 power and denominator A b to the negative 4 power , A is not equal to 0 , b is not equal to 0
Answer
A
the fraction with numerator A b to the 4th power and denominator A cubed b squared
B
the fraction with numerator A cubed b to the negative 4 power and denominator A b to the negative 2 power
C
negative the fraction with numerator A cubed b to the 4th power and denominator A b squared
D
the fraction with numerator A cubed b to the 4th power and denominator A b squared
Explanation
When dividing powers with the same base, subtract the exponents. The expression becomes A^(3−1)b^(−2−(−4)) = A²b². Choice B, (A³b⁴)/(Ab²), simplifies to A²b² and has no negative exponents.
