Mathematical Expression Calculation
D'accord, résolvons l'expression mathématique qui est donnée dans l'image : 4² - 3² + 5 On commence par calculer les carrés de 4 et de 3 : 4² = 4 * 4 = 16 3² = 3 * 3 = 9 Maintenant, remplaçons les carrés par leurs résultats dans l'expression : 16 - 9 + 5 Ensuite, soustrayons 9 de 16 : 16 - 9 = 7 Finalement, ajoutons 5 : 7 + 5 = 12 La réponse à l'expression est donc 12.
Mathematical Expression Calculation
На изображении видно математическое выражение, которое нужно вычислить. Прежде всего, выполнив математические операции в скобках, а затем выполним вычитание. 1. Сложим первые два числа и вычтем третье: \( 5223 + 1687 - 5875 \) \( 6910 - 5875 \) \( 1035 \) 2. Сложим четвертое и пятое числа и вычтем шестое: \( 2734 + 437 - 2634 \) \( 3171 - 2634 \) \( 537 \) Теперь у нас есть два результата для последнего сложения: \( 1035 + 537 \) \( 1572 \) Таким образом, итоговый результат вычисления данного выражения равен 1572.
Mathematical Expression Calculation using PEMDAS/BIDMAS Rule
La imagen muestra un problema matemático que dice así: \( (4 \cdot 5 - 2) + ( 4 \cdot 3 + 9 \cdot 3 - 2 \cdot 10) \) Para resolver este problema, vamos a seguir el orden de operaciones conocido como PEMDAS/BIDMAS, que indica que primero se deben hacer las multiplicaciones y divisiones de izquierda a derecha y luego las sumas y restas de izquierda a derecha. Así que empecemos por resolver las multiplicaciones dentro de los paréntesis: \( (4 \cdot 5 - 2) = (20 - 2) = 18 \) \( (4 \cdot 3) = 12 \) \( (9 \cdot 3) = 27 \) \( (2 \cdot 10) = 20 \) Ahora realizamos la suma y la resta dentro del segundo conjunto de paréntesis: \( (12 + 27 - 20) = (39 - 20) = 19 \) Finalmente sumamos los resultados de ambos paréntesis: \( 18 + 19 = 37 \) La respuesta es 37.
Mathematical Expression Calculation
The image contains mathematical expressions that require calculations. The word "juta" likely refers to "million" in English. I will solve the expression in option "b" as pointed out in the image: The expression is: \[ \frac{2}{5} \text{ juta} + 4.02 \text{ juta} \div 6 \] First, let's convert the fraction into a decimal so it's easier to add to the other decimal number. Since \( \frac{2}{5} \) is equal to 0.4, we have: \[ 0.4 \text{ juta} + 4.02 \text{ juta} \div 6 \] Next, perform the division before addition due to the order of operations: \[ 4.02 \text{ juta} \div 6 = 0.67 \text{ juta} \] Now, add this result to \( 0.4 \text{ juta} \): \[ 0.4 \text{ juta} + 0.67 \text{ juta} = 1.07 \text{ juta} \] Hence, the solution to the expression given in the image is: \[ 1.07 \text{ juta} \]
Solving an Arithmetic Expression using PEMDAS
The expression in the image is "6 ÷ 2(1+2)." To solve this, you should follow the order of operations, which is commonly known by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). Let's solve it step by step: 1. Calculate the expression inside the parentheses first. 1 + 2 = 3 2. The expression now is "6 ÷ 2 * 3." Next, you perform multiplication and division from left to right. 6 ÷ 2 = 3 3. Now multiply this result by the number you obtained from the parentheses. 3 * 3 = 9 Therefore, the answer to the expression is 9.
Solving a Division and Multiplication Expression with Parentheses
To solve the expression \( 8 \div 2(2+2) \), you need to follow the order of operations, which is commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). Here are the steps: 1. Parentheses: Calculate the expression within the parentheses first. \( 2+2 = 4 \) 2. Multiplication and Division: Next, you perform multiplication and division from left to right. \( 8 \div 2 \times 4 \) We do the division first because it comes before multiplication as we read from left to right. \( 4 \times 4 \) 3. Finally, you multiply the result. \( 4 \times 4 = 16 \) So the answer to the expression is \( 16 \).
