Simplify each expression. Write answers with only positive exponents. Assume that all variables represent positive real numbers.

Answer:
Step-by-step explanation:
Remember that r = r^1.
r^-1/2(r + r^3/2)
Distribute the r^-1/2 to both terms:
r^-1/2 * r^1 + r^-1/2 * r^3/2
When we multiply the same bases together, we add the exponents!
r^1/2 + r^1
Simplify:
r^1/2 + r
