Q. Write the number

2.3 \times 10^{-2}

in standard form.

\newline

Answer:

Identify Components: Identify the components of the scientific notation $2.3 \times 10^{-2}$ . In $2.3 \times 10^{-2}$ , the base number is $2.3$ and the exponent on $10$ is $-2$ .
Understand Scientific Notation: Understand that scientific notation $a \times 10^n$ means the decimal point in $a$ is moved $n$ places to the right if $n$ is positive, or to the left if $n$ is negative. $\newline$ In $2.3 \times 10^{-2}$ , since the exponent is $-2$ , we move the decimal point in $2.3$ two places to the left.
Move Decimal Point: Move the decimal point two places to the left in $2.3$ to convert it to standard form. $2.3$ becomes $0.023$ .
Write Final Answer: Write the final answer in standard form. $\newline$ The standard form of $2.3 \times 10^{-2}$ is $0.023$ .
