Answer:

LEts start with 10^1

If we have positive exponent then we add zeros

10^1= 10

$10^2=100$ (Put 2 zeros because exponent is 2)

$10^3=1000$ (Put 3 zeros because exponent is 3)

$10^4=10000$ (Put 4 zeros because exponent is 4)

$10^5=100000$ (Put 5 zeros because exponent is 5)

For negative exponent , we make a fraction . we put 1 at the top always and number as the bottom

$10^{-1}=\frac{1}{10}$ (Put 1 zero at the bottom because exponent is -1)

$10^{-2}=\frac{1}{100}$ (Put 2 zeros at the bottom because exponent is -2)

$10^{-3}=\frac{1}{1000}$ (Put 3 zeros at the bottom because exponent is -3)
