Math Problem Statement

Find the cube root of -343y^6

Solution

The expression given in the image is:

343y63\sqrt[3]{-343y^6}

To find the cube root of this expression, we can break it down into two parts:

  1. The cube root of 343-343
  2. The cube root of y6y^6

Step 1: Cube root of 343-343

3433=7\sqrt[3]{-343} = -7 because (7)3=343(-7)^3 = -343.

Step 2: Cube root of y6y^6

The cube root of y6y^6 is: y63=y2\sqrt[3]{y^6} = y^2 because y6=(y2)3y^6 = (y^2)^3.

Final Answer:

Combining these results, we get: 343y63=7y2\sqrt[3]{-343y^6} = -7y^2
