Question

find any numbers that are not in scientific notation. then, rewrite using scientific notation. you just found that 44.51 × 10⁴ is not written in scientific notation. rewrite the number using scientific notation. 44.51 × 10⁴ = ×

Explanation:

Step1: Adjust the coefficient

In scientific - notation, the coefficient should be between 1 and 10. We rewrite 44.51 as $4.451\times10^1$. So, $44.51\times10^{4}=(4.451\times10^1)\times10^{4}$.

Step2: Use the exponent rule

According to the rule $a^m\times a^n=a^{m + n}$, we have $(4.451\times10^1)\times10^{4}=4.451\times(10^1\times10^{4})=4.451\times10^{1 + 4}$.

Step3: Calculate the exponent

$1+4 = 5$. So the number in scientific - notation is $4.451\times10^{5}$.

Answer:

$4.451\times10^{5}$
