Simplify the expression:

Question

(((((-18((a)^(11))((b)^(-1))((c)^(3)))/(12((a)^(4))((b)^(3))((c)^(0))))))^(-2))

What is step by step answer without negative exponent.

Answer 1

Is this an exercise in algebra, or LISP?

(((((-18((a)^(11))((b)^(-1))((c)^(3)))/(12((a)^(4))((b)^(3))((c)^(0))))))^(-2))

(((((-18a^11(1/b)(c^3)/(12a^4)(b^3)(c^0)))))^(-2))

1/((-18a^11c^3/b) / (12a^4b^3))^2

4b^8 / (9a^14 c^6)
