✔ 最佳答案
5^-6/5^-4 = 5^-6-(-4)
when you divide exponents you subtract them.

5^-2 and then you rewite it so the exponent is positive
1/5² or 1/25


hope this helped!!!

you subtract exponents when you divide them.
5^-6/5^-4=5^-6-(-4)= 5^-2 = 1/5^2 = 1/25

5^-6/5^-4
= 5^[-6 - (-4)]
= 5^[-6 + 4]
= 5^-2
= 1/5^2
= 1/25

5 raise to the power -6 = 5^(-6)

5 raise to power -4 = 5^(-4)

Which gives you:

5^(-6) / 5^(-4)

With exponents, when you divide, you subtract:

5^(-6-(-4))
= 5^(-2)

Written without (-) exponents:

1/5^2
