Question

Solve Logarithm 5(2^x+4)=15. Round to the nearest thousandth. A.1.089 B.2.415 C.0.657 D.3.982

Answer 1

`5(2^x+4)=15\\2^x+4=3\\2^x=-1\\x\in\emptyset`

Answer 2

no solutions

Explanation:

5(2^x+4)=15

Divide each side by 5

5/5(2^x+4)=15/5

(2^x+4)=3

Subtract 4 from each side

2^x = 3-4

2^x = -1

This cannot happen so there are no solutions
