Use the properties for radicals to simplify each of the following expressions. Assume that
all variables represent positive real numbers.
radical (12x^3)/(5)

Use the properties for radicals to simplify each of the following expressions. Assume that
all variables represent positive real numbers.
radical (12x^3)/(5)
--------------
sqrt[(12x^3)/5]
Multiply numerator and denominator by 5 to get:
[sqrt(60x^3)]/5
Simplify the numerator to get:
[2xsqrt(15x)]/5
You could rewrite this as:
(2/5)xsqrt(15x)
