Use the product of powers property to simplify the numeric expression.
motikmotik

Answer:

The value of 4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}  is  4^{\dfrac{8}{15}} .

Step-by-step explanation:

We need to simplify the numeric expression using property. The expression is as follows :

4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}

The property to be used is : x^a{\cdot} x^b=x^{a+b}

This property is valid if the base is same. Here, base is x.

In this given problem, x = 4, a = 1/3 and b = 1/5

So,

4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}}=4^{\dfrac{1}{3}+\dfrac{1}{5}}\\\\=4^{\dfrac{5+3}{15}}\\\\=4^{\dfrac{8}{15}}

So, the value of 4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}  is  4^{\dfrac{8}{15}} .
