Question

12. If m = 315 and n =
V15 and n = 314, find the value of
1
т - п.
2
m² + mn+n?​

Answer 1

Answer:

If m=15-1/3 and not =14-1/3 then find the value of

(m -n)

1/(m² + mn + n)

as wek know That a - b3 = (a - b)(a² + ab + b²)

=> 1/(a² + ab + b²) (a - b)/as-b3

=> 1/(m2 + mn + n2) = (m-n)/(m3 - n3)

= (m -n) - (m- n)/(m³ - n³)

m = 15

n3 = 14

= (m - n) - (m-n)/(15 - 14)

= (m-n) - (m-n)/1

= m-n (m-n)

= 0
