Having a positive exponent means having a positive number as a power for a value or a variable.
For example:
Here, the variable x has a positive exponent because it has a power of positive (+) 2
This expression has a positive exponent because the number 1 has a power of positive (+)1 and the number 2 has a power of positive (+)4
This is not a positive exponent because the variable x has a power of negative (-)2
The positive exponent for is 
.
This expression doesn't have a positive exponent. Though number 1 in the numerator has a positive power (exponent), the number 2 in the denominator has a power of negative (-)4
The positive exponent for would be 
.
NOTE: The terms Power and Exponent have he same meanine i.e. They are the same !!!
