810 : 9 · 5 · 20 : 1000 · 70 · 2=

90*5*20/1000*70*2=

9000/1000*70*2=

9*70*2=

1260

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you just have multiplication and division, so you should perform these operations from left to right:

First, calculate the products and divisions from left to right:

810 ÷ 9 = 90 90 × 5 = 450 450 × 20 = 9000

Now, calculate the products and divisions on the right side:

1000 ÷ 70 = 14 14 × 2 = 28

Finally, divide the result on the left by the result on the right:

9000 ÷ 28 ≈ 321.43 (rounded to two decimal places)

So, the result is approximately 321.43.
