The answer of this expression is 369

We know that to solve a numerical expression, we will calculate with property base form.

When there are symbols in an expression, we first solve the numbers in order that are between:

  • Parentheses ( )
  • Brackets [ ]
  • Braces { }

The math signs calculated first in order are;

  • Power - square root
  • Multiplication - division
  • Addition - subtraction

Given the expression, the resolution will be:

5 * ( 3 + 6 )² - 6²

5 * 9² - 6²

5 * 81 - 36

406 - 36

369

So, the value of this numeric expression is 369
