Question

Solve the exponential equation using logarithms, rounding the answer to the nearest thousandth (3 decimal places). Show your work.
2 = 7^x+3

Answer 1

i'm assuming you mean 2 = 7^(x+3) ?? or is it 2 = 7^x + 3

Answer 2

no its 2=7^x+3

Answer 3

no solution then... boy that was easy huh?

Answer 4

ok..
since its the second one i wrote down, if you subtract 3 from both sides, you'll get:

-1 = 7^x

correct?

Answer 5

correct

Answer 6

now, 7^x will never ever forever be negative, no matter what x value you put in...

Answer 7

in other words, 7^x will always be a positive number. so there is no solution to your original equation.

Answer 8

ok sounds good

Answer 9

ok... have a good one man.. :)
