Answer 1

(10*2*6*4*1*9*10)+5/9=43200+5/9=43205/9=4800 

Answer 2

10*2=20
20*6=120
120*4=480
480*1=480
480*9=4320
4320*10=43200
43200*2=86400
86400+5/9=86400 и 5/9

Answer 3

To evaluate the expression 102641910*2+5:9, we need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

1. 10 * 2 = 20
2. 20 * 6 = 120
3. 120 * 4 = 480
4. 480 * 1 = 480
5. 480 * 9 = 4320
6. 4320 * 10 = 43,200
7. 43,200 * 2 = 86,400

Now let's evaluate the second part of the expression:

1. 5 ÷ 9 ≈ 0.5556 (rounded to four decimal places)

Finally, we add the two results together:

86,400 + 0.5556 ≈ 86400.5556

Therefore, the value of the expression 102641910*2+5:9 is approximately 86400.5556.
