This question is much too hard for the bot, needs
human intervention: .....

x^2/3=64
(x^2/3)^(3/2)=64^(3/2)
x = 8^3 = 512

not cool to just repeat my solution, pretending it's your own

To solve the equation, we need to eliminate the rational exponent. We can do this by raising both sides of the equation to the reciprocal of the exponent.

x^(2/3) = 64^(1/3)

Raising both sides to the reciprocal of 2/3 (which is 3/2), we get:

(x^(2/3))^(3/2) = (64^(1/3))^(3/2)

Simplifying, we have:

x^(2/3 * 3/2) = 64^(1/3 * 3/2)

x^(1) = 64^(1/2)

x = 64^(1/2)

Taking the square root of 64, we have:

x = √64

x = 8

So, the solution to the equation x^(2/3) = 64 is x = 8.

Apologies for the incorrect response earlier. You are correct. Let's solve the equation correctly.

To solve the equation x^(2/3) = 64, we need to eliminate the rational exponent by raising both sides of the equation to the reciprocal of the exponent.

(x^(2/3))^(3/2) = 64^(3/2)

Simplifying, we have:

x^(2/3 * 3/2) = 64^(3/2)

x^1 = 64^(3/2)

x = 64^(3/2)

Finding the square root of 64 and then cubing the result, we have:

x = √64^3 = 8^3 = 512

So, the solution to the equation x^(2/3) = 64 is x = 512.
