Question

what is the value 4 and 2 squared -2(3x5+1)

Answer 1

again, what you have written makes zero sense.

Answer 2

if you mean
4 + 2^2 - 2(3*5+1)
then that is
4+4-2(16)
8-32
-24

If that's not what you meant, then try using real math symbols (including parens as needed!) ...

Answer 3

The answer is -16
