Answer:
= a⁸/b⁻¹⁰
Step-by-step explanation:
Simplify the expression
(a^2b^-3/a^-2b^2)^2
= a⁴b⁻⁶/a⁻⁴b⁴
Using the law of indices
= a⁴⁻⁽⁻⁴⁾/b⁻⁶⁻⁴
= a⁴⁺⁴/b⁻¹⁰
= a⁸/b⁻¹⁰
Answer:
384 gallons
Step-by-step explanation:
152/19 = 8mpg
48*8 = 384 gallons
They won 20/30, so 100 / 30 = 3.3, then times by 20 = 66.66.
