10^2/10^5. Because both numbers have the same bases, simply subtract the exponents (the top from the bottom). Since 5 is bigger than 2, the remaining answer will be in the denominator. 1/10^3. However, you can also raise the number to the numerator by adding a negative to the exponent. 10^-3 is also acceptable, even recommended.

3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power
381.8 divided by 10 to the fifth power equals 0.003818
2 to the power of 20 divided by 4 to the power of 10 is equal to one.
1,000,000,000,000.
When dividing numbers with the same base, you subtract the exponents. In this case, 10 to the 5th power divided by 10 to the 2nd power is equal to 10 to the power of 5 minus 2, which simplifies to 10 to the 3rd power. Therefore, the result is 1,000.

3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power
10 to the 8th power divided by 10 to the 7th power is 10
8.2 x 102 ÷ 6.3 x 104 ≈ 1.302 x 10-2
0.8 divided by 10 to the second power = 0.08
