Question

Solve for x withouth using logarithms 2/3= (81/16)^3x

Answer 1

81 = 3^4

16 = 2^4

hope this helps

Answer 2

2/3=(16/18)^-3x
=(2^4/3^4)^-3x
=(2/3)^-12x
since bases are same.
1=-12x
x=-1/12 answer

Answer 3

32^x= 4^x+1 Solve without using logarithms

Answer 4

\[32^{x}= 4^{(x+1)}\]
32 can be written as 2^5, and 4 as 2^2
\[2^{5x}= 2^{2(x+1)}\]
Now can you solve for x?
