If a + b = 25, then (a – 15)3 + (b – 10)3 is:
Answer & explanation
Correct answer: option 2
If a + b = 25, then (a – 15)3 + (b – 10)3
Put the value of a = 15 and b = 10
(a – 15)3 + (b – 10)3 = (15 – 15)3 + (10 – 10)3
(a – 15)3 + (b – 10)3= 0
If a + b = 25, then (a – 15)3 + (b – 10)3 is:
Correct answer: option 2
If a + b = 25, then (a – 15)3 + (b – 10)3
Put the value of a = 15 and b = 10
(a – 15)3 + (b – 10)3 = (15 – 15)3 + (10 – 10)3
(a – 15)3 + (b – 10)3= 0
