Question 579496
{{{0.000498=4.98*0.0001=4.98*(1/10000)=4.98*10^(-4)}}}
To convert to scientific notation, you need to think of the number as a product of two factors. The first factor will have the same digits as the original number, but will only have one non-zero digit in front of the decimal point. The other factor will be made of a 1 and a bunch of zeros, like 10000, or 0.001, and you will have to write it as a power of ten.
10,000={{{10^4}}}
0.001={{{10^(-3)}}}
The exponent is the number of zeros (counting the one before the decimal point for small numbers like 0.001).
