Find the quotient.

5^7/5^3

a.5^4
b.5^10
c.8^15
d.8^21

if the base is the same (5, in this case)

... you can subtract the denominator exponent from the numerator exponent

5^7/5^3 = 5^(7-3) = 5^4

because
5*5*5*5*5*5*5
---------------------- = 5*5*5*5
5*5*5

To find the quotient of 5^7/5^3, you can subtract the exponents because when you divide two powers with the same base, you subtract the exponents.

The exponent of 5^7 is larger than the exponent of 5^3. So, subtract the exponent of 5^3 from the exponent of 5^7.

7 - 3 = 4

Therefore, the quotient is 5^4. Therefore, the answer is choice (a) 5^4.

To find the quotient of two exponential expressions, you need to subtract the exponents of the same base. In this case, both expressions have a base of 5.

We have 5^7 divided by 5^3.

To divide exponential expressions with the same base, you subtract the exponents.

So, 5^7 / 5^3 = 5^(7-3) = 5^4.

Therefore, the quotient is 5^4.

Therefore, the correct answer is a. 5^4.
