Final answer:
To expand the expression (4x + 6y)⁴, the coefficient of the term containing the 4th power of Pascal's Triangle is 4.
Step-by-step explanation:
To expand the expression (4x + 6y)⁴, you can use Pascal's Triangle to find the coefficients of each term. The 4th power of Pascal's Triangle represents the coefficients for the 4th term. In general, the coefficients can be found by using the formula (nCk) where n is the exponent and k is the term number. In this case, the 4th term has a coefficient of 1, which can be found by using (4C3) = 4/3! = 4.
