Wasn’t sure how to write this out : - )

amid [387]

we are given

$\frac{\sqrt[3]{7}\sqrt{7}}{\sqrt[6]{7^5}}$

we can write it in terms of exponents

$\frac{7^{\frac{1}{3}}*7^{\frac{1}{2}}}{7^{\frac{5}{6}}}$

Firstly , we will simplify numerator

$\frac{7^{\frac{1}{3}+\frac{1}{2}}}{7^{\frac{5}{6}}}$

now, we can add exponents

$\frac{7^{\frac{5}{6}}}{7^{\frac{5}{6}}}$

we can cancel it

and we get

$=1$ ............Answer

marta [7]

Answer:

8/8

Step-by-step explanation:

There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).

Basically, multiply how many fourths (four per pie) by how many pies there are.

4 x 2 = 8

There are 8 pieces.
