Question

Jenna calculated several numbers in her calculator. The result displayed 1.8E-4 on the calculator screen. Which equivalent number(s) does this represent? Select all that apply.

Answer 1

When you move the decimal to the left, it adds 1 to your exponent. So if you move it to the left 4 times, you will get 0.00018.

Answer 2

1.8E-4 also means 1.8 x 10^-4, or  0.00016.
