Simplify expressions involving rational exponents

Full solution

Q. Simplify. Assume all variables are positive.

\newline

y^{\frac{3}{7}} \cdot y^{\frac{10}{7}}

\newline

Write your answer in the form

A

or

\frac{A}{B}

, where

A

and

B

are constants or variable expressions that have no variables in common. All exponents in your answer should be positive.

\newline

______

Identify and Apply Property: Identify the equation and apply the property of exponents for multiplication. $\newline$ When multiplying two exponents with the same base, we add the exponents: $\newline$ $y^{\frac{3}{7}} \times y^{\frac{10}{7}} = y^{\frac{3}{7} + \frac{10}{7}}$
Add Exponents: Add the exponents. $\newline$ $\frac{3}{7} + \frac{10}{7} = \frac{(3 + 10)}{7} = \frac{13}{7}$ $\newline$ So, $y^{\frac{3}{7}} \times y^{\frac{10}{7}} = y^{\frac{13}{7}}$
Write Final Answer: Write the final answer in the form $A$ or $\frac{A}{B}$ , where $A$ and $B$ are constants or variable expressions that have no variables in common. All exponents in your answer should be positive. $\newline$ The final answer is $y^{\frac{13}{7}}$ , which is already in the correct form.
