Chapter 12.6, Problem 67STP

To determine

To calculate: the standard form of $7.3\times {10}^{-2}.$

Answer to Problem 67STP

The standard form is $0.073$ .

Explanation of Solution

Given information:

  $7.3\times {10}^{-2}$

Formula used:

Convert negative exponent into positive exponent.

Convert decimal into fraction form .

Then convert fraction form into decimal .

Calculation:

Consider ,

  $7.3\times {10}^{-2}$

  $\begin{array}{l}=7.3\times \frac{1}{{10}^2}\\ =7.3\times \frac{1}{100}\\ =\frac{7.3}{100}\\ =\frac{73}{1000}\\ =0.073\end{array}$

Hence, the standard form is $0.073$ .
