Answer:

#211#

Explanation:

In expressions which involve different operations, always count the number of TERMS first. They are separated by #+ and -# signs.

Each term simplifies to a single answer and these are added or subtracted in the final step.

Within each term, the order is:

  • brackets
  • powers and roots
  • multiply and divide
