Question

Which expression represents the sixth term in the binomial expansion of (2a - 3b)10?

Answer 1

Answer

2,737,152a⁵b⁵

Explanation

(2a - 3b)¹⁰ = (2a)¹⁰ - 10(2a)⁹(3b) + 47(2a)⁸(3b)² - 144(2a)⁷(3b)³ - 212(2a)⁶(3b)⁴ + 352(2a)⁵(3b)⁵

The 6th term in this expression is 352(2a)⁵(3b)⁵

352(2a)⁵(3b)⁵ = 352 × 2⁵a⁵ × 3⁵b⁵

                         = 352 × 32 ×243 ×a⁵b⁵

                         = 2,737,152a⁵b⁵
