Question

# Look at the example problem. Estimate the product (5.3 X 10-4) X (4.8 X 107) and show your work. Is your solution close to the estimate?

Answer

25,440. The estimated product is 25,000, so the solution is close to the estimate.

- Multiply 5.3 and 4.8 to get 25.44.
- Add the exponents of 10 to get 10^-4+7=10^3.
- Multiply 25.44 and 10^3 to get 25,440.
