20³ + 17³ / 20+17 - 20×17
To solve the expression 20³ + 17³ / 20+17 - 20×17, we need to follow the order of operations, also known as PEMDAS.
- First, calculate the exponents: 20³ = 20 × 20 × 20 = 8000 and 17³ = 17 × 17 × 17 = 4913.
- Next, perform the division: 4913 / (20+17) = 4913 / 37 = 132.945…
- Then, perform the multiplication: 20 × 17 = 340.
- Finally, subtract the result of step 3 from the sum of steps 1 and 2: 8000 + 132.945… - 340 = 7932.945…
Therefore, the answer to the expression 20³ + 17³ / 20+17 - 20×17 is approximately 7932.945.
