Simplify Term 1
-243^1/5
Simplify the rational exponent:
-2431/5
Analyze Fractional Exponent:
ab/c = (c√a)b
Take the cth root of a
Then raise that to the power of b
In this case, a = -243, b = 1, and c = 5
Evaluate the 5th root of -243:
5√-243 = -3 since -35 = -243
as seen in our Exponent Lesson
Raise this value to the power of 1:
Therefore, we can write -2431/5 = -3
Final Answer
-2431/5 = -3
