Question

how do you write 0.50 in scientific notation? × 10

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leq|a|\lt10$ and $n$ is an integer.

Step2: Rewrite 0.50

To get $a$ in the range $1\leq|a|\lt10$, we rewrite $0.50$ as $5.0\times10^{- 1}$. Here, $a = 5.0$ and $n=-1$.

Answer:

$5.0\times10^{-1}$
