Simplify Scientific Notation: 10×10^-3×10^5 Multiplication Problem

Question

Reduce the following equation:

$10\times10^{-3}\times10^5=$

00:00 Simply

00:04 Any number to the power of 1 is always equal to itself

00:08 We'll use this formula in our exercise, and raise to the power of 1

00:11 According to the laws of exponents, multiplication of powers with equal base (A)

00:14 equals the same base raised to the sum of the exponents (N+M)

00:17 We'll use this formula in our exercise

00:20 Note that we're adding a negative factor

00:36 Positive times negative is always negative, therefore we subtract

00:48 And this is the solution to the question

$10^3$
