Question

I’m having issues with natural logs and logs, and this problem is on my pre-call homework. Can anyone help me out?

2^x+7 = 3

Answer 1

Explanation:

23

Answer 2

Explanation:

2^x + 7 = 3

2^x = -4 this cannot be solved

Maybe you meant

2^(x+7) = 3

LOG both sides to get

(x+7) LOG 2 = LOG 3

x+7 = log3/log2 subtract 7 from both sides to get

x = - 5.415
