Question

When is it appropriate to use scientific notation instead of standard form?

Answer 1

Answer:

It is appropriate to use scientific notation instead of standard form when a number is very large. Option C is correct.

Explanations:

Scientific notation is expressed in the form;

$A\times10^n$

where

A is any real number between 1 and 10

n is any positive integer

Scientific notation is the best way to express large numbers in multiples of 10s. It makes a large number be conveniently written in decimal form. For instance, the standard value 190,000,000 can be written in a scientific form as:

$1.9\times10^8$

Hence we can conclude that it is appropriate to use scientific notation instead of standard form when a number is very large.
