x=2e21
Alternative Form
x≈0.067668
Evaluate
ln(x×2)=−2
Find the domain
More Steps

Evaluate
x×2>0
Use the commutative property to reorder the terms
2x>0
Rewrite the expression
x>0
ln(x×2)=−2,x>0
Use the commutative property to reorder the terms
ln(2x)=−2
Convert the logarithm into exponential form using the fact that logax=b is equal to x=ab
2x=e−2
Evaluate the power
2x=e21
Multiply by the reciprocal
2x×21=e21×21
Multiply
x=e21×21
