(enter your answer as a whole number or fraction)
$10^5 \div 10^6 = $

Explanation:

Step1: Evaluate the base first

$4-8=-4$

Step2: Apply zero exponent rule

$(-4)^0=1$

Step3: Apply quotient of exponents rule

$10^5 \div 10^6 = 10^{5-6}=10^{-1}$

Step4: Rewrite negative exponent as fraction

$10^{-1}=\frac{1}{10}$

Answer:

1. $1$
2. $\frac{1}{10}$
