question
write the number $2.2 \times 10^5$ in standard form.

Explanation:

Step1: Recall the meaning of \(10^5\)

\(10^5 = 10\times10\times10\times10\times10 = 100000\)

Step2: Multiply 2.2 by \(10^5\)

To convert \(2.2\times10^5\) to standard form, we multiply 2.2 by 100000. When multiplying a decimal by a power of 10, we move the decimal point to the right by the number of zeros in the power of 10. Here, \(10^5\) has 5 zeros, so we move the decimal point in 2.2 five places to the right.
\(2.2\times100000 = 220000\)

Answer:

220000
