Question

Solve 2^x + 3 = 7

Answer 1

x ≈ 0.94

x ≈ –5.19

x ≈ –0.19

x ≈ 2.81

Answer 2

2 ^x = 7 - 3 = 4
2^2 = 4
so x = 2

Answer 3

x ≈ –0.19

Answer 4

(x+3) ln(2) = ln(7)
x = ln(7)/ln(2) - 3

Answer 5

x ≈ –0.19

Answer 6

oh ok - its 2^(x+3) right
question is confusing - best to use parentheses in case like this
