how do you write 7.22 in scientific notation? × 10

Answer:

$7.22\times 10^{0}$

Explanation:

Step1: Recall scientific - notation rule

Scientific notation is $a\times 10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Determine $a$ and $n$ for 7.22

For the number 7.22, $a = 7.22$ and since $7.22=7.22\times1$, and $1 = 10^{0}$, so $n = 0$.
