If `3^(n+4)-3^(n+2)=8`, then what is the value of n?

n/4-2=3 what is the value of n?

If 3^(2n - 1) = 1/(27^(n - 3)) , then the value of n is

If 3^(2n-1)= (1)/(27^(n-3)) , then the value of n is

If the numbers -3,4n-2,5n+1 are in AP, what is the value of n?

(i) If (n!)/(2.(n-2)!): (n!)/(4!.(n-4)!) = 2:1 , find the valye of n. (ii) If ((2n)!)/(3!(2n-3)!): (n!)/(2!(n-2)!) = 44:3 , then find the value of n.

If 2^(2n-1)=(1)/(8^(n-3)), then the value of n is a -2 b.2 c.0 d.3
