Answer:
1.) Add -15 and 9.
Step-by-step explanation:
We have been given an expression [tex](-2)^3+4\div (-15+9)(3)-4[/tex]. We are asked to choose the correct step to evaluate our given expression.
We will use order of operations PEMDAS to solve our given problem.
P = Parenthesis,
E = Exponent,
M/D = Multiplication or division (from left to right).
A/S = Addition or subtraction (from left to right).
So, first of all, we need to remove parenthesis. To remove parenthesis, we have to add -15 and 9, therefore, 1st option is the correct choice.
