(m)[(-4)+(1)/(4)]+((7)/(-16))=(-4)+[(1)/(4)+((7)/(-18))]

[((-4)/(7))+(1)/(4)]+([7]/[-16])-([-4]/[7])+[(1)/(4)+((7)/(-16))]

1-(3)/(16)+(1.4)/(1.2)((3)/(16))^2- (1.4.7)/(1.2.3)((3)/(16))^3 + …..=

[{((1)/(7^(2)))^(-2)}^((1)/(3))]^((1)/(4))=7^(m), is -(1)/(3)(b)(1)/(4)(c)-3(d)2

Show- [(-4/7)+1/4]+(-7/16)=(-4/7)+[1/4+(-7/16)]

The value of tan[cos^(-1)((4)/(5))+tan^(-1)((2)/(3))] is (6)/(17) (b) (7)/(16) (c) (16)/(7) (d) none of these

(1)/(2)+(3)/(2).(1)/(4)+(5)/(3).(1)/(8)+(7)/(4).(1)/(16)+....=

((1)/(1.4 )+ (1)/(4.7 ) +(1)/(7.10 )+(1)/(10.13 )+(1)/(13.16)) is equal to

((1)/(1xx4)+(1)/(4xx7)+(1)/(7xx10)+(1)/(10xx13)+(1)/(13xx16))=?
