Question

Rewrite the expression with a positive rational exponent. Simplify, if possible.100-1/2

Answer 1

`100-(1)/(2)`

We need that the 100 has a 2 in the denominator. To do this, we can multiply on top and bottom by 2:

`100\cdot(2)/(2)=(200)/(2)`

Now, we can make the subtraction:

`(200)/(2)-(1)/(2)=(199)/(2)`

The answer is 199/2
