Question

To multiply two numbers in scientific notation, use properties to rearrange the terms. Then use the exponent rules to simplify.

(2.1 • 103) • (3 • 1018)

Answer 1

Multiplying numbers that are in scientific notation is fairly simple because multiplying powers of 10 is so easy. Here’s how to multiply two numbers that are in scientific notation: 1. Multiply the two decimal parts of the numbers. Suppose you want to multiply the following: (4.3 x 10 5)(2 x 10 7)

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

To Simplify:

• $(2.1*10^3) * (3*10^{18})$

Solution:

$:\implies (2.1*10^3) * (3*10^{18}) \\\\:\implies 2.1 * 10^3 * 3 * 10^{18} \\\\:\implies (2.1*3) * (10^3*10^{18}) \\\\:\implies 6.3 * 10^{18+3} \\\\\bf{:\implies 6.3 * 10^{21}}$

Hope it helps!!!
