Scientific notation

Question

Express 0.0002077 in scientific notation

Answer 1

Scientific notation is how to write it as a number between 1-10, so 2.077.

How many decimal places did you move? Four. Multiplying by 10 moves the decimal right, but to go from 2.077 to our given number, we move left by multiplying by 1/10, or 10^-1.

2.077 x 10^-4
