## j.giudice13 3 years ago What is the solution to the equation 2^(1 + 2x )= 3 ?

1. dpaInc

2^(1 + 2x )= 3 take the log_2 of both sides: 1+2x = log_2 3 subtract 1 from both sides: 2x = (log_2 3) - 1 divide by 2 x = [(log_2 3) - 1]/2

2. j.giudice13

-1/2 isnt an option....

3. dpaInc

you didn't specify the way you wanted the solution... and -1/2 is not what I came up with. it's x = [(log_2 3) - 1]/2 did you want a calculator answer?

4. j.giudice13

umm, yea let me see what that looks like

5. j.giudice13

i dont have a calculator :(

6. dpaInc

computer calculator?

7. j.giudice13

i have so many windows up lol

just one more won't hurt http://www.wolframalpha.com

i just need an answer to see if i did this right

10. TuringTest

what did you get? I gave you a calculator...

11. j.giudice13

my computer will crash. its old i got .185

http://www.wolframalpha.com/input/?i=%5B%28log_2+3%29+-+1%5D%2F2 if that doesn't work use a calculator from the applications section. Those have been there since time immemorial.

0.292... is the "right" answer. If you want the most accurate answer you take the thing with the log.

thank you very much. simple is all i need
