How would you expand (x+5y)^5?
Firstly, explain briefly what you understand from the question.
=> (x+5y)5 = (x+5y)(x+5y)(x+5y)(x+5y)(x+5y)
What would be the binomial expansion of form (x+y), brief explanation of pascals triangle and what it shows about coefficients.
Go on to prompt them to finding the correct solution.
(x+5y)5 = x5 + 25x4y + 250x3y2 + 1250x2y3 + 3125xy4 + 3125y5
