To solve the equation x^3 = 125/27, we can take the cube root of both sides:
∛(x^3) = ∛(125/27)
x = ∛(125/27)
To simplify this, we can rewrite 125 as 5^3 and 27 as 3^3:
x = ∛(5^3/3^3)
x = (5/3) * ∛1
Since the cube root of 1 is 1, we have:
x = 5/3
Therefore, the solution to x^3 = 125/27 is x = 5/3.

True or False: square roots of perfect squares are rational numbers (4 points)
true, because square roots of perfect squares are integers and can be turned into a ratio
false, because square roots of perfect squares are never ending and non repeating

True. The statement "square roots of perfect squares are rational numbers" is true.
A perfect square is a number that can be expressed as the square of an integer. For example, 9, 16, and 25 are perfect squares because they can be written as 3^2, 4^2, and 5^2, respectively.
The square root of a perfect square will be the integer that, when squared, gives the original perfect square. For example, the square root of 9 is 3, the square root of 16 is 4, and the square root of 25 is 5.
Rational numbers are numbers that can be expressed as a ratio of two integers. In this case, the square roots of perfect squares can be expressed as a ratio of the integer square root to 1.
Therefore, the square roots of perfect squares are rational numbers.
