Question

[no]
08/2"+25n = -8"+1
find the value of n.​

Answer 1

Hii

you are welcome in my ans

2^n +( 2^n)4= - ( 2^n )3+1

let 2^n =t

t + t^4 = - t^3 +1

t^4 +t^3 +t - 1= 0

(t - (-1 + sqrt5)/2)( t +(1 sqrt5)/2)(t - i)(t + i)=0

so value of n is

2^n = i

2logn = logi

n = logi/logn

.....

hope it may helps you
