1. [tex]$5+2^3 \cdot(22+11)-3^2 \cdot(4+5)=$[/tex]



Answer :

To solve the given expression [tex]\(5+2^3 \cdot(22+11)-3^2 \cdot(4+5)\)[/tex], we'll follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Here’s the step-by-step solution:

1. Parentheses: First, solve the expressions inside the parentheses.

[tex]\[ (22 + 11) = 33 \][/tex]
[tex]\[ (4 + 5) = 9 \][/tex]

2. Rewrite the expression with the evaluated parentheses:

[tex]\[ 5 + 2^3 \cdot 33 - 3^2 \cdot 9 \][/tex]

3. Exponents: Next, we handle the exponents.

[tex]\[ 2^3 = 8 \][/tex]
[tex]\[ 3^2 = 9 \][/tex]

4. Rewrite the expression with the evaluated exponents:

[tex]\[ 5 + 8 \cdot 33 - 9 \cdot 9 \][/tex]

5. Multiplication and Division: Now, we perform any multiplication and division from left to right.

[tex]\[ 8 \cdot 33 = 264 \][/tex]
[tex]\[ 9 \cdot 9 = 81 \][/tex]

6. Rewrite the expression with the evaluated multiplications:

[tex]\[ 5 + 264 - 81 \][/tex]

7. Addition and Subtraction: Finally, perform addition and subtraction from left to right.

[tex]\[ 5 + 264 = 269 \][/tex]
[tex]\[ 269 - 81 = 188 \][/tex]

Hence, the result of the expression [tex]\( 5 + 2^3 \cdot (22 + 11) - 3^2 \cdot (4 + 5) \)[/tex] is [tex]\(\boxed{188}\)[/tex].
