Simplifying (8a^-3)^-2/3
Let's break down how to simplify the expression (8a^-3)^-2/3 step by step:
Applying the Power of a Power Rule
- Rule: (x^m)^n = x^(m*n)
Applying this rule to our expression:
(8a^-3)^-2/3 = 8^(-2/3) * (a^-3)^(-2/3)
Simplifying the Numerical Term
- Rule: x^(-n) = 1/x^n
Simplifying 8^(-2/3):
8^(-2/3) = 1/8^(2/3)
- Rule: x^(m/n) = (n√x)^m
Simplifying 1/8^(2/3):
1/8^(2/3) = 1/(∛8)^2 = 1/2^2 = 1/4
Simplifying the Variable Term
- Rule: (x^m)^n = x^(m*n)
Simplifying (a^-3)^(-2/3):
(a^-3)^(-2/3) = a^(-3)*(-2/3) = a^2
Combining the Simplified Terms
Now we have:
8^(-2/3) * (a^-3)^(-2/3) = (1/4) * a^2
Final Simplified Form
Therefore, the simplified form of (8a^-3)^-2/3 is a^2/4.
