Let’s break it into parts: (3k^2)^3 is equal to 3•3•3•(k•k)•(k•k)•(k•k), or: (3^3)(k^6) = 27(k^6) 27(k^6)•k^3= 27k^9
[Summary: if there N exponent out side the parentheses of something, you multiply the exponent on the outside by the exponent on the inside, Ex. (k^2)^3=k^(2•3)=k^6. When multiplying two variables you add their exponents together. Ex. k^(6)•k^(3)=k^(6+3)=k^(9)]
