According to exponential law, when powers are divided,
their exponents are subtracted.
n^a / n^b =
n^a-b
Take a look at each variable by itself. Subtract the
exponents. Remember that minus negative becomes
addition.
a^3 / a^-2 = a^(3 - -2) =
a^5
b^-3 / b^-2 = b^(-3 - -2) =
b^-1
c^-1 / c^3 = c^(-1 - 3) =
c^-4
The variables with positive exponents will be part of
the numerator and the variables with negative exponents will be part of the
denominator.
numerator:
2a^5
denominator: 3b^1c^4
The
entire fraction, both numerator and denominator, is raised to the 3rd
power.
numerator:
(2a^5)^3
denominator:
(3b^1c^4)^3
According to exponential law, to find the power
of a power, you multiply the exponents. Remember to also distribute the exponent 3 to
the contants.
numerator: 2^3 * a^(5*3) =
8a^15
denominator: 3^3 * b^(1*3) * c^(4*3) =
27b^3c^12
The final simplified answer
is...
(8a^15) /
(27b^3c^12)
