(8.1)(4.2) 10^(8+3)
34.02 * 10^11
3.402 * 10^12
(8.1*10^8)*(4.2*10^3)
34.02 * 10^11
3.402 * 10^12
Step 1: Multiply the decimal parts: 8.1 * 4.2 = 34.02
Step 2: Multiply the exponent parts: 10^8 * 10^3 = 10^(8+3) = 10^11
Step 3: Combine the results: 34.02 * 10^11
To express the answer in scientific notation and retain all nonzero decimal places, we can write it as 3.402 * 10^12.
