Question

Help me solve this exponential equation plz!!

256^(5x)=64^(x+4)

Answer 1

4^4=256 and
4^3=64 so
256^(5x)=4^(4*5x)
and
64^(x+4)=4^(3*(x+4))
u can substitue and solve from there

Answer 2

2^8^(5x) = 2^6^(x+4)
40x=6x+24
34x=24
x=12/17

Answer 3

I guess 4 would have been easier
20x=3x+12
17x=12
x=12/17 :)

Answer 4

lol

Answer 5

it would still come out to 12/17 either method correct?

Answer 6

yup as mrjoselson's steps showed. 4 would just be faster

Answer 7

Thank you both =)
