Question

Solve x3 = 125 over 27.

Answer 1

Take the cube root of both the left and right sides. What times what times what equals 125? What times what times what equals 27? Same with the x. x * x * x= x^3 because when multiplying x, we add the exponents. 5 * 5 * 5= 125. 3 * 3 * 3= 27.

x^3= 125/27
x= 5/3 or 1.6666667

Hope this helps! :)

Answer 2

Please express exponentiation with "^":  Solve x^3 = 125 / 27.

Find the cube root of both sides.  The cube root of x^3 is just x.
The cube root of 125 is 5, and the cube root of 27 is 3.  What is the value of x?
