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

Answer:

$5.291\times 10^{12}$

Step-by-step explanation:

Given expression,

$(4.81\times 10^{16})(1.1\times 10^{-4})$

$=4.81\times 1.1\times 10^{16-4}$   $(\because a^m.a^n=a^{m+n})$

$=5.291\times 10^{12}$

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,

$5.291\times 10^{12}$
