45(288/9.3-4.6^2)-1065e^-1.5 and y=x^2-e^0.5x+x

This is confusing.
What is ‘e’?
Is it a variable, or the exponential function exp()?
Please clarify what you want to do.

Its the exp() function. I want to know how to type these equations in matlab separately.

That’s easy, then. The first one’s not an equation, so I supplied the missing left-hand side:
q = 45*(288/9.3-4.6^2)-1065*exp(-1.5)
y = x.^2-exp(0.5.*x)+x
I assume here the missing operators are implied multiplication. Since ‘x’ may be a vector (I don’t know from what you’ve written), I used the element-wise array operators (.^) and (.*) in place of the vector operators (^) and (*). They will work with both scalars and vectors.
