Q. Write the number

3.2 \times 10^{-5}

in standard form.

\newline

Answer:

Understand standard form: Understand what standard form means. $\newline$ Standard form refers to writing the number without using exponents, which means moving the decimal point to the right or left depending on the exponent of $10$ .
Move decimal point left: Move the decimal point to the left because the exponent is negative. $\newline$ Since the exponent is $-5$ , we move the decimal point $5$ places to the left. $\newline$ $3.2 \rightarrow 0.32 \rightarrow 0.032 \rightarrow 0.0032 \rightarrow 0.00032 \rightarrow 0.000032$
Write in standard form: Write the number in standard form. $\newline$ After moving the decimal point $5$ places to the left, the number in standard form is $0.000032$ .
