Question

Hey there

Answer 1

Answer:

A

Step-by-step explanation:

Just had this on a test!

Answer 2

(160 * 243)^1/5

To simplify the above expression first step is to factor the numbers. Therefore,

$(160*243)^{\frac{1}{5}} = ((2*2*2*2*2*5)*)(3*3*3*3*3)^{\frac{1}{5}}$

=$(2^5*5*3^5)^{\frac{1}{5}}$

= $(2^5)^{\frac{1}{5}} *(5)^{\frac{1}{5}} *(3^5)^{\frac{1}{5}}$

=$2 * (5)^{\frac{1}{5}} *3$

= $6*(5)^{\frac{1}{5}}$

= $6\sqrt[5]{5}$

So, correct choice is A.
