Question

(4,25 умножить на 16/51- 17/18:8,5) умножить на (3/11) в квадрате

Answer 1

(4,25*16/51-17/18:8,5)*3/11²=15/242
4,25*16/51=425/100*16/51=17/4*16/51=4/3
17/18:8,5=17/18:85/10=17/18:17/2=17/18*2/17=1/2
4/3-1/2=8/6-3/6=5/6
3/11²=3/11*3/11=9/121
5/6*9/121=15/242

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) to ensure the correct sequence of operations:

1. First, calculate the expression inside the first parentheses: (4,25 * 16/51 - 17/18 ÷ 8.5)

2. Next, perform the multiplication and division inside the first parentheses: (4.25 * 16/51 - 17/18 ÷ 8.5) (4.25 * 0.313725 - 17/18 ÷ 8.5) (1.33390625 - 17/18 ÷ 8.5)

3. Now, calculate the division inside the first parentheses: (1.33390625 - 0.08888888888) (1.33390625 - 0.08888888888) 1.24501736112

4. Now, multiply the result by (3/11)^2: 1.24501736112 * (3/11)^2

5. Calculate (3/11)^2: (3/11)^2 = (3/11) * (3/11) = 9/121

6. Finally, multiply the previous result by 9/121: 1.24501736112 * 9/121

Now, let's calculate this:

1.24501736112 * 9/121 ≈ 0.092662057

So, the final result is approximately 0.0927.
