# How do you write an expression in exponential form

Exponential expressions Video transcript - [Voiceover] What I hope to do in this video is, start with a exponential expression that's in a fairly straightforward form and then turn it into one in a hairier form. And let's actually just do it.

For example, a 2-decimal scientific format displays as 1. Follow these steps to apply the scientific format to a number. Select the cells that you want to format. For more information, see Select cells, ranges, rows, or columns on a worksheet.

To cancel a selection of cells, click any cell on the worksheet.

On the Home tab, click the small More button next to Number. In the Category list, click Scientific. Using the small arrows, specify the Decimal places that you want to display.

The number that is in the active cell of the selection on the worksheet appears in the Sample box so that you can preview the number formatting options that you select.

## SUMMARY: Forms of a complex number

To quickly format a number in scientific notation, click Scientific in the Number Format box Home tab, Number group.

The default for scientific notation is two decimal places. A number format does not affect the actual cell value that Excel uses to perform calculations. The maximum limit for number precision is 15 digits, so the actual value shown in the formula bar may change for large numbers more than 15 digits.

Cells that are formatted with the General format do not use a specific number format. However, the General format does use exponential notation for large numbers 12 or more digits. To remove the exponential notation from large numbers, you can apply a different number format, such as Number.

Expand your Office skills.To write a fraction as a decimal, you just need to divide - in this case, divide 1 by 27 to get Let's try another one. Write 4^-2 as a fraction and as a decimal. Solution We can solve both of these equations by translating from exponential form to logarithmic form.

(a) Write the given equation in logarithmic form: \$4^{-x^2} = 1/64\$. Provide more opportunities to work with exponential expressions.

For example, ask the student to find the unknown in equations such as = or = Ask the student to explain (in oral or written form) the process of evaluating exponential expressions. Guide the student to use correct mathematical terminology such as base, exponent, and factor. It is usually much easier to first convert the logarithm form into exponential form.

In that form we can usually get the answer pretty quickly.

a \({\log _4}16\) Show Solution. PROPERTIES OF LOGARITHMS • Use properties of logarithms to expand or condense logarithmic expressions. • Use logarithmic functions to model and solve real-life problems. What You Should Learn. 3 To solve a logarithmic equation, you can write it in exponential form.

How do you express in exponential form as a power of 6? It is expressed as * 10 6. Note that the decimal moved 6 places to the left, hence the 10 to the 6th power.
