Question

Find 7.5×1041.25×10−9. Write your answer in scientific notation.

Answer 1

To multiply numbers in scientific notation, multiply the coefficients and add the exponents. 7.5x10^41 * 1.25x10^-9 = 9.375x10^32.

Step-by-step explanation:

To multiply numbers in scientific notation, you multiply the coefficients and add the exponents.

1. The coefficient of 7.5 is 7.5.
2. The coefficient of 1.25 is 1.25.
3. The exponent of 10 in 7.5x10^41 is 41.
4. The exponent of 10 in 1.25x10^-9 is -9.

Multiplying the coefficients gives us 7.5x1.25 = 9.375.

Adding the exponents gives us 41 + (-9) = 32.

Therefore, 7.5x10^41 * 1.25x10^-9 = 9.375x10^32 in scientific notation.
