Question

16*8*2*5 7*2*13*5 Вычисли удобным способом.

Answer 1

1) (16*2)(8*5)=1280
2)(7*5)(2*13)=910

Answer 2

I can help you with your math problem. Here is how I would solve it:

First, I would simplify the expression by using the distributive property of multiplication. That means I can multiply each term inside the parentheses by the term outside the parentheses. For example, $(16*8)*2*5 = 16*(8*2*5) = 16*80$. Similarly, $(7*2)*13*5 = 7*(2*13*5) = 7*130$.

Then, I would add the two simplified terms together. That means I can use the commutative property of addition, which says that the order of the terms does not matter. For example, $16*80 + 7*130 = 7*130 + 16*80$.

Finally, I would multiply the numbers to get the final answer. That means I can use the standard algorithm of multiplication, which involves multiplying each digit by each digit and adding the partial products. For example, $7*130 = (7*100) + (7*30) = 700 + 210 = 910$.

So, the final answer is:

$$ (16*8)*2*5 + (7*2)*13*5 = 16*80 + 7*130 = 1280 + 910 = 2190 $$

I hope this helps you understand how to solve this problem. If you have any other questions, feel free to ask me.
