problems with the formulas

[parijs]

I try the following formulas to solve, unfortunately without success, so I ask the public for help.

1.) =(16*LN(14))/(-LN(14)+19)
2.) =6.8*EXP(8.2+(4*(6*13^3)/((1+7*4)*((5*1.8+32)+459.6))))

Have a look at Basic4android - ExpressionEvaluator it should help you out.

I've already seen it 15 times but I understand LN (n) base e not And any use of it gives me

Undeclared variable 'ln' is used before it was assigned any value.

I suppose you want the equations in B4A language.

1.) = (16 * Logarithm(14, cE)) / (-Logarithm(14, cE) + 19)
2.) = 6.8 * Power(cE, (8.2 + (4 * (6 * Power(13, 3) / ((1 + 7 * 4) * ((5 * 1.8 + 32) + 459.6)))))

Best regards.
