Simplify 14 to the fifteenth power over 14 to the fifth power

14^15/14^5 = 14^10 (14 to the tenth power)

14^10

Step-by-step explanation:

When dividing expressions with exponents that have the same bases, you subtract the exponent from the denominator from the exponent of the numerator.

14^15/14^5    gets rewritten as  

14^(15-5),  or 14^10

Think if it as x^15/x^5, we can rewrite it like

()()    We cancel out 5 x's from the numerator and denominator, leaving

()/1     which simplifies to x^10/1    or just x^10

if you mean

then it's c. 8, -7/3

but if you mean

then it is
