1.

7^n-1 = 2^2n-1 tomorrow is exam please tell me​

Answer»

Answer:

bro -1 is on power both side or SOMETHING else. use bracket to simplify your QUESTION

i THINK -1 is in POWERS so

according to my thinking

7^[n-1]=2^[2n-1]

[7^n]/7=[2^2n]/2

[7^n]/[4^n]=7/2

[7/4]^n=7/2                {a^n/b^n=[a/b]^n}

bro i think your question is WRONG there is mistake in RHS of question i.e it is not 2^2n but it is 26n

so

[7/2]^n=[7/2]

on compairing both side

n=1 ans
