Question

What is (4.81x 10^16) (1.1x10^-4) in scientific notation?

Answer 1

4.81 * 10 ¹⁶ * 1.1 * 10 ⁻⁴
= 5.291 x 10 ¹²

Answer 2

`5.291* 10^(12)`

Explanation:

Given expression,

`(4.81* 10^(16))(1.1* 10^(-4))`

`=4.81* 1.1* 10^(16-4)`
`(\because a^m.a^n=a^(m+n))`

`=5.291* 10^(12)`

Since, a number is in scientific notation if it is written as the product of a number between 0 to 9 and an exponent of 10.

Hence, the scientific notation of the given problem is,

`5.291* 10^(12)`
