[7+2(5 - 9)2]/[(4+1)2 - 3(22)
I am confused as to what the "(22)" means. Is it twenty-two, 2 multiplied by 2, 2 squared?
Its 2 Times the Square Root of 2
are there other hidden √'s?
Is 2(5 - 9)2 = 2*(5-9)^2 ? or √(5-9)^2 or √√(5-9)
You can copy and paste the √ character. Use it an "^" for powers, and try clearing things up.
To simplify the given expression, we will use the order of operations (also known as PEMDAS). This is a set of rules that tells us which operations to perform first.
PEMDAS stands for:
1. Parentheses: Simplify expressions inside parentheses first.
2. Exponents: Evaluate any exponents next.
3. Multiplication and Division: Perform multiplication and division from left to right.
4. Addition and Subtraction: Finally, perform addition and subtraction from left to right.
Let's break down the given expression step by step:
First, we simplify the expression inside the parentheses:
5 - 9 = -4
Now we substitute this value back into the expression:
7 + 2(-4)2
Multiplication is performed next:
2(-4) = -8
Substitute this value back into the expression:
7 + (-8)2
Now we perform the exponentiation:
(-8)2 = 64
The expression becomes:
7 + 64
Lastly, we perform addition:
7 + 64 = 71
So, the final answer is 71.
