Question

If 4 power 7 + 4power7 + 4power7 + 4 power 7 by 2 power 7 plus 2 power 7 equals to 2 X then x​

Answer 1

Acc. To me,

Answer is 4^7/2   here ^ means power

--------------------------------------------------------------

Just take 4^7 common from numerator and 2^7 from denominator

4^7(1+1+1+1)/2^7(1+1)=2x

4^7(4)/2^7(2)=2x

4 is added in num and 2 is added in denom

4^8/2^8=2x

if you change 2^8 in term of 4 then =4^4

4^8/4^4=2x

denom power goes up and minus

4^8-4=2x

4^4=2x

4^4/2=x

Change 2 in term of 4 then =4^1/2

4^4/4^1/2=x

4^4-1/2=x

4^7/2=x

I Hope you understand my answer
