Question

5(a−4) 3 + 2(5a−3) 5 + 6(a−4) 15

Answer 1

Answer:

Solution :-

→ 5(a - 4)3 + 2(5a - 3)5 + 6(a - 4)15 = 0

↦15a - 60 + 50a - 30 + 90a - 360 = 0

↦ 15a + 50a + 90a - 60 - 30 - 360 = 0

↦ 65a + 90a - 90 - 360 = 0

↦ 155a - 450 = 0

↦ 155a = 450

↦ a = 450/155

↦ a = 90/31

↦ a = 2.9032

∴ The answer of this question is 2.9032
