-5*3+((-1)^3-3)^2

Question

-5*3+((-1)^3-3)^2  I need to double check my answer to this problem.  I came up with -6

Answer 1

If the problem is this:

 

-5*3 + ((-1)³ -3)²

 

Exponent inside the parentheses first:

-5*3 + ((-1)³ - 3)²

 

Since (-1)³ = -1 * -1 * -1 = -1:

 

-5*3 + (-1 - 3)²

 

Since (-4)² = 16:

 

-5*3 + 16

 

-15 + 16

 

Answer:
