Question

Please help me with this problem!

Answer 1

Hii!

Answer:

Explanation:

Use the rule of exponents.

If we divide two numbers with the same bases, we subtract the exponents.

7^-6/7^2=7^-6-2=7^-8

Now, if we have a negative exponent, we flip over the number.

7^-8=1/7^8

Great job!

Answer 2

The choice A ;

`\frac{1}{ {7}^(8) }`

Explanation:

`\frac{ {7}^( - 6) }{ {7}^(2) } = \frac{ {7}^( - 6 - 2) }{1} = {7}^( - 8) = \frac{1}{ {7}^(8) } \\ \\ \\ or. \: \frac{ {7}^( - 6) }{ {7}^(2) } = \frac{1}{ {7}^( 2 + 6) } = \frac{1}{ {7}^(8) }`
