In the given expression (y+4)⁴ we need to expand it using the Binomial Theorem. The binomial coefficients for the expansion are determined by the fourth row of Pascal's Triangle: 1, 4, 6, 4, 1. These coefficients represent the number of ways each term can be obtained by combining the powers of y and 4.

To expand the expression, we raise y to powers decreasing from 4 down to 0, while the powers of 4 increase from 0 up to 4. The coefficients are multiplied by the corresponding powers of y and 4 and summed together to obtain the expanded form. ...
