how do you write 1.2 in scientific notation? × 10

Answer:

$1.2\times 10^{0}$

Explanation:

Step1: Recall scientific - notation form

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

Step2: Determine $a$ and $n$ for 1.2

For the number 1.2, $a = 1.2$. Since $1.2=1.2\times10^{0}$ (because $10^{0}=1$), $n = 0$.
