a power of 10
-144/10
The simplest way is to write it as -0.2 which is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its rational equivalent is -2/10 which can be simplified, if required.
1.92*10-2

10 to the second power is the inverse of 10 to the negative second power. 10 to the 2nd power is 100 so the inverse of 100 is 1/100 or .01 so 10 to the negative second power is written as 10-2 which is equal to 1/100 or 0.01.
10-4 = 1/104 = 0.0001 = 1/10000
