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
