1D Element Wise Arithmetic Operators: Mismatched delimiters?

function surfaceArea = surfaceBalloon(Volume,M)
   radius = sqrt((3*Volume)/((pi)(2+M)));  % We are given a volume and we must solve for the radius in order to plug into formula below
    surfaceArea = pi*(radius)^2(2+sqrt(1+(M)^2);
   
    
end

What am I doing wrong? I thought you only use dot operators when multiplying, dividing, or raising to a power with another array. These are just being multiplied/raised by scalar values.

variable, use parentheses. Otherwise, check for mismatched delimiters.

Hello you are missing a multiplication sign, in the denominator (line 2). Multiplication with parentheses is not supported without the multiplication operator.

radius = sqrt((3*Volume)/(pi*(2+M)));

I'd recommend cutting down on the brackets:

radius = sqrt(3*Volume / (pi*(2+M)));
