1,5²-4,5+2

Answer

To solve the expression \(1.5^2 - 4.5 + 2\), we will follow the order of operations:

Calculate \(1.5^2\): \[ 1.5^2 = 2.25 \]
Substitute \(2.25\) into the expression: \[ 2.25 - 4.5 + 2 \]
Perform the subtraction: \[ 2.25 - 4.5 = -2.25 \]
Now add \(2\): \[ -2.25 + 2 = -0.25 \]

Therefore, the final result is: \[ -0.25 \]

Question 2

1,5²-4,5+2

Answer

To solve the expression \(1.5^2 - 4.5 + 2\), we will follow the order of operations: 1. Calculate \(1.5^2\): \[ 1.5^2 = 2.25 \] 2. Substitute \(2.25\) into the expression: \[ 2.25 - 4.5 + 2 \] 3. Perform the subtraction: \[ 2.25 - 4.5 = -2.25 \] 4. Now add \(2\): \[ -2.25 + 2 = -0.25 \] Therefore, the final result is: \[ -0.25 \]
