А) 59 * 64 + 59 * 36= в) 63 * 356 − 556 * 63= г) −99 * 12 − 99 * 88= пж решить распределительным законом 50баллов

Answer 1

Ответ:

. А)59(64 + 36) = 59 ∙ 100 = 5900

Б) 63(356 - 556) = 63 ∙ (-200) = -12600

В) -99(12 + 88) = -99 ∙ 100 = -9900

Answer 2

#### Task A: 59 * 64 + 59 * 36 To solve this equation, we can use the distributive property of multiplication over addition. The distributive property states that for any numbers a, b, and c, the product of a and the sum of b and c is equal to the sum of the products of a and b, and a and c. So, for the equation 59 * 64 + 59 * 36, we can apply the distributive property as follows: 59 * 64 + 59 * 36 = 59 * (64 + 36) Now, we can simplify the expression inside the parentheses: 64 + 36 = 100 Substituting this back into the equation: 59 * (64 + 36) = 59 * 100 Finally, we can calculate the result: 59 * 100 = 5900 Therefore, the value of 59 * 64 + 59 * 36 is **5900**. #### Task B: 63 * 356 - 556 * 63 Similarly, we can use the distributive property to solve the equation 63 * 356 - 556 * 63: 63 * 356 - 556 * 63 = 63 * (356 - 556) Simplifying the expression inside the parentheses: 356 - 556 = -200 Substituting this back into the equation: 63 * (356 - 556) = 63 * (-200) Calculating the result: 63 * (-200) = -12600 Therefore, the value of 63 * 356 - 556 * 63 is **-12600**. #### Task C: -99 * 12 - 99 * 88 Applying the distributive property to the equation -99 * 12 - 99 * 88: -99 * 12 - 99 * 88 = -99 * (12 + 88) Simplifying the expression inside the parentheses: 12 + 88 = 100 Substituting this back into the equation: -99 * (12 + 88) = -99 * 100 Calculating the result: -99 * 100 = -9900 Therefore, the value of -99 * 12 - 99 * 88 is **-9900**. I hope this helps! Let me know if you have any further questions.
