Math Problem Statement

Solve the expression 6^2 - (5 - 4) + 2(8 - 2^2) ÷ 8.

Solution

The equation shown in the image is:

62(54)+2(822)÷86^2 - (5 - 4) + 2(8 - 2^2) \div 8

Let’s solve it step by step, following the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Step 1: Parentheses and Exponents

  • First, solve any operations inside parentheses:
    • 54=15 - 4 = 1
    • 22=42^2 = 4, so 84=48 - 4 = 4

The equation becomes: 621+2(4)÷86^2 - 1 + 2(4) \div 8

Step 2: Exponents

  • Now, evaluate the exponent 62=366^2 = 36.

The equation is now: 361+2(4)÷836 - 1 + 2(4) \div 8

Step 3: Multiplication and Division (left to right)

  • Multiply 2(4)=82(4) = 8.
  • Now, divide 8÷8=18 \div 8 = 1.

The equation simplifies to: 361+136 - 1 + 1

Step 4: Addition and Subtraction (left to right)

  • Subtract: 361=3536 - 1 = 35.
  • Then add: 35+1=3635 + 1 = 36.

Final Answer:

3636
