Evaluate: $\frac{10^{-2}5^0}{10^{-3}}$
To simplify this expression, I can use the rules of exponents for powers of 10 and powers of 5. For powers of 10, I know that $10^{-n}$ means $\frac{1}{10^n}$, so I can rewrite the numerator and denominator as fractions. For powers of 5, I know that $5^0$ means 1, so I can simplify that as well. So, the expression becomes $\frac{\frac{1}{10^2}\cdot 1}{\frac{1}{10^3}}$. So, the expression becomes $\frac{1}{10^2}\cdot \frac{10^3}{1}$. So, the expression becomes $\frac{10^3}{10^2}$. To simplify this fraction, I can use another rule of exponents: $10^a\div 10^b=10^{a-b}$. So, the expression becomes $10^{3-2}$. Finally, I can subtract the exponents and get $10^1$.
