    flip the fraction when you do that sign of exponent would change

    not 18 3^4 is same as 3 times 3 times 3 times 3 which isn't equal to 18

    To raise a number to a negative power, first, ignore the negative and just raise the number to the positive exponent. Then write 1 over the number. Examples: \(5^{-3} \) start with \(5^3 = 125\). Now write 1 over that. Answer \(\dfrac{ 1}{125} \) \(6^{-2}\) start with \(6^2 = 36\). Now write 1 over the number. Answer \(\dfrac{1}{36} \)
