Multiplication
a%5Em+%2A+a%5En+=+a%5E%28m%2Bn%29

Division

a%5Em%2Fa%5En+=+a%5E%28m-n%29
Powers
+%28a%5Em%29%5En+=+a%5E%28m%2An%29


149,600,000 km
Sun, Distance to Earth
This can be written as 1.496*10^8
Suppose you need to write a number 2000000000000000000
this can be written as 2 * 10^15

10%5E5+%2A+10%5E6+=+10%5E%286%2B5%29=+10%5E11

5%5E11%2F5%5E5+=+5%5E%2811-5%29+=+5%5E6
