Question

11^-5 ÷ 11^-3 please help!!!!​

Answer 1

11^ -2 = 1 / 11^2 = 1/121

Explanation:

11^-5 ÷ 11^-3

When the bases are the same, we subtract the exponents when dividing

11 ^ ( -5 - -3)

11 ^ ( -5+3)

11 ^ -2

We know that a^ -b = 1/a^b

1/ 11^2

1/121

Answer 2

Explanation:

`a^(-m)=(1)/(a^(m))\\\\Therefore, (1)/(a^(-m))=a^(m)`

`11^(-5)` ÷
`11^(-3) = 11^(-5) * 11^(3)\\\\` {
`a^(m)*a^(n) = a^(m+n)` }

`11^(-5+3) \\\\= 11^(-2)`
