Question

Explain how you could write the mixed number 45 3/8 in
scientific notation.

Answer 1

`4.5375*10^1`

Explanation:

we know that

`45(3)/(8)=45+(3)/(8)=45+0.375=45.375`

Convert decimal number in scientific notation

A number expressed in scientific notation has the form

`a*10^(n)`

where

`1\leq a < 10`

n is a integer

Expressing 45.375 in this form means writing the number as a value between 1 and 10

so

For a=4.5375,n=1

`45.375=4.5375*10^1`
