what is the answer

Question

Which is the simplified form of the expression ?

Answer 1

6^6

= 46,656

(a^b)^c = a^bc

a^b/a^e = a^(b-e)

multiply exponents "on top of each other" -4 x -9 = 36

subtract exponents when one is in the numerator and the other in the denominator 36/6 = 6

final exponent is just 6 with base 6 or 6^6
