Chapter 4.7, Problem 69CCR

To determine

To express the number in standard form.

Answer to Problem 69CCR

Standard form of a number is, $3.08\times {10}^{-4}=0.000308$

Explanation of Solution

Given information: The number is, $3.08\times {10}^{-4}$

Concept used: Numbers that do not contain exponents are written in standard form.

Calculation : Standard form of a number is obtained as,

  $\begin{array}{l}3.08\times {10}^{-4}\\ 3.08\times {10}^{-4}=0.000308\left(\text{Move the decimal point 4 places to the left}\right)\\ \text{Hence, standard form of a number is, }3.08\times {10}^{-4}=0.000308\end{array}$
