#### Work Step by Step

Recall, in order to solve problems involving order of operations, we use the PEMDAS rule. First Priority: P - parentheses and other grouping symbols Second Priority: E - exponents Third Priority: M/D - Multiplication or division, whichever comes first from the left to the right Fourth Priority: A/S - Addition or subtraction, whichever comes first from the left to the right Apply the exponents first, and then multiply to obtain: $=5(-27)-4(9)+6(-3)+1$ $=-135-36+(-18)+1$ Add/subtract from the left to the right to obtain: $=-171+(-18)+1$ $=-189+1 \\=-188$
