Which calculation can be used to find the value of y in the equation y3 = 27?
The given question is based on cubes and cube roots.
Answer: The value of y in the equation y3 = 27 is y = 3.
Let us find the solution of the equation y3 = 27
The cube for the number (x) is represented as x3 or x-cubed
- cube of number = x3
- cube root of a number = ∛x
y3 = 27
y = ∛27 = ∛(3 x 3 x 3) = ∛[(3)3] = 3/3 = 31 = 3
y = 3.
