Answer:
-48
Step-by-step explanation:
Use PEMDAS (Parentheses, Exponents, Multiply or Divide, Add or Subtract) to solve.
[tex]3^3-15*5[/tex]
Since there is no parentheses, solve the exponent first.
[tex]3^3[/tex] is the same thing as [tex]3*3*3[/tex] which is equal to 27.
The equation now looks like this
[tex]27-15*5[/tex]
Next multiply and/or divide (in this case we only need to multiply).
[tex]27-75[/tex]
Now add and/or subtract.
In this problem we only need to subtract.
27-75=-48
