Question

11^-5 ÷ 11^-3 please help!!!!​

Answer 1

Answer:

11^ -2  = 1 / 11^2 = 1/121

Step-by-step 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

Answer:

Step-by-step explanation:

$a^{-m}=\frac{1}{a^{m}}\\\\Therefore, \frac{1}{a^{-m}}=a^{m}$

$11^{-5}$ ÷ $11^{-3} = 11^{-5} * 11^{3}$            {$a^{m}*a^{n} = a^{m+n}$  }

                   $11^{-5+3} \\\\= 11^{-2}$
