Question

How do you figure 1.8 times 10 to the third power divided by 9 times 10 to the 7th power

Answer 1

To do 1.8 x 10 to the 3rd power, you first transform 10 to the 3rd into 10000. After done that, multiply those numbers together. (Or just move the decimal point over three spots to the right.) and you’ll get your answer of 1,800.
For 9 x 10 to the 7th power, you turn 10 into 10000000, (or move the decimal point after the nine seven spots to the right) and you’ll get an answer of 90000000.
