Question

6.3*10^-3 in ordinary number

Answer 1

The answer is -6300

Explanation:

6.3 x 10^-3

1) Accoring to PEMDAS, we must do 10^-3 first. 10 x 10 x 10 = 1,000, then we add the negative
6.3 x -1000

2) Now we just move the decimal on 6.3 three times to the right, then add the negative
6.3 x -1000
-6300

Answer 2

$6.3\cdot 10^{-3}=6.3\cdot\frac{1}{10^3}=\frac{6.3}{1000}=\frac{63}{10000}=0.0063$
