Let f (x) = (x4 - y4)
= (x2 - y2) (x2 + y2)
= (x - y) (x + y) (x2 + y2)
and g(x) = (x6 - y6)
= (x3)2 - (y3)2
= (x3 + y3) (x3 - y3)
= (x + y) (x2 - xy + y2) (x - y)(x2 + xy + y2)
= (x - y) (x + y) (x2 - xy + y2)
(x2 + xy + y2)
? HCF of [f(x), g(x)] = (x - y) (x + y)
= x2 - y2
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
Subtract 20, 25, 30, 35, 40, 45 from successive numbers. So 0 is wrong.
NA
Each previous number is multiplied by 2.
? 8 m shadow means original height = 12 m
? 1 m shadow means original height = 12/8 m
? 100 m shadow means original height = (12/8) x 100 m
= (6/4) x 100 = 6 x 25 = 150 m
Let 8% of 96 = y of 1/25
? (8 x 96)/100 = y/25
? y = (8 x 96 x 25)/100 = 192
Since the principal is not given, so data is inadequate.
