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);
Error in solution: Line: 2 Column: 36

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)));
