Which of these is correct?

(3 ^ 6)/(3 ^ 4) = 1/9

(4 ^ 6)/(4 ^ 3) = 0

(5 ^ 8)/(5 ^ 6) = 25

(6 ^ 7)/(6 ^ - 5) = 36

1 answer

The correct equation is:

(3 ^ 6)/(3 ^ 4) = 1/9

The other equations are incorrect:

(4 ^ 6)/(4 ^ 3) = 256/64 = 4

(5 ^ 8)/(5 ^ 6) = 390625/15625 = 25

(6 ^ 7)/(6 ^ - 5) = 279936/0.000064 = 4374000000
