4^2 + 6.5^2 - 3^3/3^2 = 16 + 42.25 - 3 =
thank you
You are welcome.
To solve this expression, let's break it down step by step using the order of operations (PEMDAS/BODMAS).
Step 1: Exponents - start by evaluating any exponents.
4^2 = 4 * 4 = 16
6.5^2 = 6.5 * 6.5 = 42.25
3^3 = 3 * 3 * 3 = 27
3^2 = 3 * 3 = 9
Now, the expression becomes:
16 + 42.25 - 27/9
Step 2: Division - perform any division.
27/9 = 3
Now, the expression becomes:
16 + 42.25 - 3
Step 3: Addition and Subtraction - perform additions and subtractions from left to right.
16 + 42.25 = 58.25
58.25 - 3 = 55.25
Therefore, the value of the expression 4^2 + 6.5^2 - 3^3/3^2 is 55.25.
