Question

Y ^-7 / y ^-13 20 POINTS PLEASE HELP

Answer 1

The answer is

`{y}^(6)`

Explanation:

`\frac{ {y}^( - 7) }{ {y}^( - 13) }`

To solve the expression we use the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's

`\frac{ {a}^(x) }{ {a}^(y) } = {a}^(x - y)`

So we have

`\frac{ {y}^( - 7) }{ {y}^( - 13) } = {y}^( - 7 - - 13) = {y}^( - 7 + 13)`

We have the final answer as

`{y}^(6)`

Hope this helps you
