Then it will be 2t...
You should learn properties of indices and explore as many as questions you can
it will be beneficial to you
ya sure thanks
2^n-1 + 2^n+1 =320 can u solve these please
yes, sure but where you want solution?
for this you have to ask this question on brainly
it can not possible in comment section ??
Obviously, it's not possible
ok

2^n+4-2^n+2=3
(2ⁿ)(2⁴)-(2ⁿ)(2²)=3
Let 2ⁿ=a
a(2⁴)-a(2²)=3
16a-4a=3
12a=3
a=1/4
2ⁿ=a
2ⁿ=1/4
2ⁿ=(1/2²)
2ⁿ=2^-2
Bases are equal,exponents must be equal.
n=-2
