What is 0.0540 in scientific notation?

Answer 1

Scientific notation is in the form of a x 10^n, where 0

First, move the decimal point to make the number less than 10 but greater than 0. .0540→5.4.

Next, count how many decimal places you moved the decimal and in what direction. .0540→.540(1 place right)→5.4(2 places right). You moved it two places to the right.

Since you made the number larger, you must make the exponent smaller to compensate. And since you moved it 2 places, you will make the exponent -2. (n must be negative since you positively increased a).

So: .0540 = 5.4 x 10^-2
