Question

Solve the following exercise

a7ya5x \frac{a^{7y}}{a^{5x}}

Video Solution

Solution Steps

00:00 Simply
00:03 When dividing powers with equal bases
00:07 The power of the result equals the difference of the exponents
00:10 We'll use this formula in our exercise, and subtract the exponents
00:14 And this is the solution to the question

Step-by-Step Solution

Let's consider that in the given problem there is a fraction in both the numerator and denominator with terms of identical bases. Hence we use the property of division between terms of identical bases in order to solve the exercise:

cmcn=cmn \frac{c^m}{c^n}=c^{m-n} We apply the previously mentioned property to the problem:

a7ya5x=a7y5x \frac{a^{7y}}{a^{5x}}=a^{7y-5x} Therefore, the correct answer is option A.

Answer

a7y5x a^{7y-5x}
