Math Problem Statement

Find the value of the cube root of 27.

Solution

The question in the image asks to find the value of 273\sqrt[3]{27}, which is the cube root of 27.

Solution:

The cube root of a number xx is a number yy such that y3=xy^3 = x.

  1. Start with 2727:
    We need to find yy such that y3=27y^3 = 27.

  2. Test simple values:

    • 13=11^3 = 1 (too small)
    • 23=82^3 = 8 (still too small)
    • 33=273^3 = 27 (perfect!)
  3. Therefore, 273=3\sqrt[3]{27} = 3.

Final Answer:

The value is 3.
