How to correctly input complex multiband functions in Raster Calculator?

[المشرف العام]

I'm trying to compute a MTVI2 (Modified Triangular Vegetation Index - Improved) and EVI (Enhanced Vegetation Index) from Landsat 8 imagery.

My formulas are as follow (I'm using the model builder):

MTVI2=

1.5*(1.2*("%Band 5%"-"%Band 4%")-2.5*("%Band 4%"-"%Band 3%")) / SquareRoot(Square(2*"%Band 5%"+1)-(6*"%Band 5%"-5*SquareRoot("%Band 4%")-0.5))

EVI=

("%Band 5%"-"%Band 4%") / ("%Band 5%"+6*"%Band 4%"-7.5*"%Band 2%"+1)

I've tried threating the bands as floats with the same results. Any suggestions?
