Question

Solving Exponential Equations with Unequal Bases

2x + 3 = 7

Answer 1

what is all this about exponential equations...?

Answer 2

Did you read what Turing posted in your earlier question?

Answer 3

I need help, obviously.

Answer 4

But I am afraid you did not type the question properly. It's like saying "how tall is this building?" and then you show me a tree...

Answer 5

no let me re-write the problem.

Answer 6

if the questions is just
2x + 3 = 7
then it is a simple linear equation

Answer 7

ah...

Answer 8

you should have written this as
2^(x+3)=7
take the log base 2 of both sides, then tell me wht you have

Answer 9

\( x = \log_2 7 -3 \)

Answer 10

2^(x+3)=7
log 2^(x+3)= log 7
(x + 3) = log(2)7
x = log(2)7 -3

Answer 11

or , x = log7/ log2 -3

Answer 12

Sorry, but im not comprehending any of this.

Answer 13

which part
