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)= x+ 25x4y + 250x3y+ 1250x2y+ 3125xy+ 3125y5
