multiply the numbers and add the powers of 10. Use the commutative property of multiplication to rearrange factors as needed.
1.2*10^3 * 1.4*10^2
= 1.2*1.4 * 10^3*10^2
= 1.68 * 10^(3+2)
= 1.68 * 10^5
You have to do a final adjustment in some cases to make sure that the number is less than 10 and at least 1.0
3.5*10^3 * 8.1*10^-1
= 3.5*8.1 * 10^(3-1)
= 28.35*10^2
= 2.835*10^3
In scientific notation, what is the product of 1.2 × 10^3 and 1.4 × 10^2? Express your answer to two significant figures.
Can you also explain how to do this? Thanks!
