Question

log function: 2^x−4+10=22

Answer 1

I assume it's this\[2^{x-4} + 10 = 22\]and not this \[2^{x}-4+10\]
How can you simplify the equation?

Answer 2

yes it's the first one

Answer 3

any ideas for first steps?

Answer 4

I have no idea, that's why I'm asking

Answer 5

2^x=22-10+4
2^x=16
Now transform this into a log equation.

Answer 6

The painfully obvious one, using the inverse property of addition and the fact that if b = c, then a+b = a+ c, is\[2^{x-4}+10=22\]\[2^{x-4}+10 + (-10) = 22 + (-10)\]\[2^{x-4}+0 = 12\]\[2^{x-4}=12\]

Answer 7

If you know how to exponential equations as logarithmic ones, you can do that without much difficulty now.

Answer 8

Ok, I see. Thank You
