Question 1118571: Question on evaluating expressions:
The expression is 30x2^y
x=-2/5 and y= 5/8
I believe it should be solved as follows:
30-(2/5)^2 x 5/8 which = 299/10
Is this the correct way to evaluate the expression? I've never seen one like this before so I'm guessing.
Thank you!

It's 30 x^2 y !
You find this in polynomials in two variables like P(x.y) = Ax^2 y^3 + B x^2 y^2
