Answer:
(a.) 27^4/3 = 81, (b.) 36^3/2 = 216, (c.) (1/8)^2/3 = 1/4, (d.) 128^5/7 = 32
Explanation:
All these expressions can be converted in square roots.
In order to do this, we can picture the fractional exponents as exponent / index
(a.) So for this first problem, we would have the cube root of
or
.
We must do the equation inside the radical first (i.e.,
) to get
= 81
We can follow these same steps for the remaining equations:
(b.)
=
=
= 216
(c.)
=
=
=
=
(d.)
=
= 32
