Question

Help!!

Simplify the following expression.

Answer 1

A.

Explanation:

Whenever you decide exponents, you actual subtract them

Taking the first part

`\frac{21 {m}^(42) }{3 {m}^(21) }`

21 divided by 3 is 7, right

Now the small numbers, 42 divided by 21. Since they are exponents, we do 42 minus 21. Making it 21.

You'd do the same for n and p, ending up with A
