Simplify expression. Answers should only have positive exponents. Assume all variables are positive.

(4x^2 y^-1/3)^3/14

so would it be x^2(3/14) and y^-1/3(3/14)?

To simplify the expression (4x^2 y^-1/3)^3/14, you need to apply the exponent rules and simplify each part of the expression separately.

Let's start with (4x^2 y^-1/3). Raised to the power of 3/14, each term inside the parentheses will be raised to that exponent.

For the first term, 4x^2, raise the coefficient and the variable to the power of 3/14:
4^(3/14) * (x^2)^(3/14) = (2^2)^(3/14) * x^(2 * 3/14) = 2^(2 * 3/14) * x^(6/14) = 2^(6/14) * x^(3/7).

For the second term, y^-1/3, raise the variable to the power of 3/14:
(y^-1/3)^(3/14) = y^(-1/3 * 3/14) = y^(-1/14).

Now, put the simplified terms back together:
(4x^2 y^-1/3)^3/14 = 2^(6/14) * x^(3/7) * y^(-1/14).

So the simplified expression is 2^(6/14) * x^(3/7) * y^(-1/14).

Note: If you need a decimal approximation for the exponent, you can calculate using a calculator.

To simplify the expression (4x^2 y^-1/3)^3/14, we can apply the exponent rules.

First, let's simplify the expression inside the parentheses:
(4x^2 y^-1/3)^3.

To simplify the coefficients, we raise 4 to the power of 3, which is 64.

For x^2, we multiply the exponents: x^2 * 3 = x^6.

For y^-1/3, we multiply the exponent by 3: (-1/3) * 3 = -1.

So, inside the parentheses, we have 64x^6 y^-1.

Now, let's simplify the expression as a whole:
(64x^6 y^-1)^(3/14).

To simplify the exponent, we raise both the numerator and denominator to the power of 3/14:

64^(3/14) * x^(6 * 3/14) * y^(-1 * 3/14).

Using the laws of exponents, we can simplify further:

64^(3/14) = 2^(6 * 3/14) = 2^(18/14) = 2^(9/7).

x^(6 * 3/14) = x^(18/14) = x^(9/7).

y^(-1 * 3/14) = y^(-3/14).

Putting it all together, the simplified expression is:

2^(9/7) * x^(9/7) * y^(-3/14).

Note that all the exponents are positive.
