Question

Convert 2.47x10^-3 to regular notation​

Answer 1

Answer:

$\large\boxed{2.47\times10^{-3}=0.00247}$

Step-by-step explanation:

METHOD 1:

$\text{Use:}\ 10^{-n}=\dfrac{1}{10^n}\\\\2.47\times10^{-3}=2.47\times\dfrac{1}{10^3}=2.47\times\dfrac{1}{1000}=\dfrac{2.47}{1000}\\\\=\dfrac{2.47\times100}{1000\times100}=\dfrac{247}{100000}=0.00247$

METHOD 2:

$a\times10^n\\\\\text{If}\ n0\ \text{then move the comma n places to the right.}$

$\text{Therefore}\ 2.47\times10^{-3}=0\underbrace{.002}_{\leftarrow3}47$
