Найдите значение выражения:а) 9² +19б) 17² - 209в) 6³ :4г) 2² *3²д) (15-7)² : 2³ Напишите плиз даю 8 баллов а если лутший то +4

Answer 1

А)9*9+19= 100
Б)17*17-209 = 289 -209 = 80
В) 6*6*6 :4 =36*6:4= 36/4 * 6= 9*6 =54
Г)2*3= 6 в квадрате = 36
Д)(15-7) в кВ : 2 в кубе= 8 в кВ : 2 * 2*2= 64/8= 8
Можно 8 не возводить в квадрат а просто сократить.

Answer 2

а) 9² + 19: To find the value of this expression, we need to calculate 9 squared (9²) and then add 19 to the result.

9 squared is equal to 81, so the expression becomes:

81 + 19 = 100

Therefore, the value of the expression 9² + 19 is 100.

б) 17² - 209: To find the value of this expression, we need to calculate 17 squared (17²) and then subtract 209 from the result.

17 squared is equal to 289, so the expression becomes:

289 - 209 = 80

Therefore, the value of the expression 17² - 209 is 80.

в) 6³ : 4: To find the value of this expression, we need to calculate 6 cubed (6³) and then divide the result by 4.

6 cubed is equal to 216, so the expression becomes:

216 : 4 = 54

Therefore, the value of the expression 6³ : 4 is 54.

г) 2² * 3²: To find the value of this expression, we need to calculate 2 squared (2²) and then multiply it by 3 squared (3²).

2 squared is equal to 4, and 3 squared is equal to 9, so the expression becomes:

4 * 9 = 36

Therefore, the value of the expression 2² * 3² is 36.

д) (15-7)² : 2³: To find the value of this expression, we need to calculate the square of the difference between 15 and 7 [(15-7)²] and then divide it by 2 cubed (2³).

The difference between 15 and 7 is 8, so the expression becomes:

8² : 2³ = 64 : 8 = 8

Therefore, the value of the expression (15-7)² : 2³ is 8.

I hope this helps! Let me know if you have any further questions.
