You can use the rules of PEMDAS to solve this equation.

Explanation:

PEMDAS stands for the order of operations, or the order in which equations are completed.

  • Parentheses
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

To solve this equation, we can follow PEMDAS.
First, parentheses. What is inside the parentheses?

#3^2-5#

To solve what is in the parentheses, now we address the second term in PEMDAS, exponents. We need to solve all of the exponents in the problem.

#3^2=9#

Now we can continue to solve the parentheses.

#9-5=4#

We simplify the equation.

#24-(4)#

Now, we simply solve.

#24-4=20#

The answer to the equation is 20, and is found by using PEMDAS.
