Solve : (a) `3n+7=25` (b) `2p-1=23`

Solve: 3n + 7 = 25

Solve : 7+3p=25

Solve: 2p-1 = 23

Solve : 2.3-:100

Solve : 3^(2x+4)+1=2.3^(x+2)

The value of cot(sum_(n=1)^23 cot^-1(1+sum_(k=1)^n 2k)) is (a) 23/25 (b) 25/23 (c) 23/24 (d) 25/26

The value of cot(sum_(n=1)^(2)cot^(-1)(1+sum_(k=1)^(n)2k)) is (a) (23)/(25) (b) (25)/(23) (c) (23)/(24) (d) (25)/(26)
