Answer:
[tex]5^{-2}[/tex]
Step-by-step explanation:
When dividing with the same bases (but different exponents), the quotient will have the same base, but the power will be the result of the two powers subtracted..
[tex]\frac{5^{4} }{5^{6} } = 5^{-2}[/tex]
**Think of it this way--> 4 - 6 = -2,so just keep the bases and change the exponent.
