true statement with Ln() returns invalid expression

[VCTaylorA]

when you write a false equation, like $1=2$, SpeedCrunch normally returns "invalid expression".

However, when you input a true identity like $3*ln(4)=ln(4^3)$, it also returns "invalid expression".

this does not change if you write a variation like 3ln(4)=ln(4^3), or (3*ln(4))=ln(4^(3))

In speedcrunch "a = b" means "assign value b to variable a". It is not an equation. Even 1=1 is invalid expression, because it is required to have variable on the left side.
