Answer 1

1 пример равен 7250 ,

Answer 2

725x(9+1) = 725x9 + 725x1

To find the value of this expression, we can apply the distributive property of multiplication over addition.

First, let's calculate 725 multiplied by 9: 725 x 9 = 6525

Next, let's calculate 725 multiplied by 1: 725 x 1 = 725

Now, let's add the two results together: 6525 + 725 = 7250

So, the value of 725x(9+1) is 7250.

75x(10+1) = 971

Similarly, we can apply the distributive property to this expression.

First, let's calculate 75 multiplied by 10: 75 x 10 = 750

Next, let's calculate 75 multiplied by 1: 75 x 1 = 75

Now, let's add the two results together: 750 + 75 = 825

So, the value of 75x(10+1) is 825.

971 + 21 + 8x385

To find the value of this expression, we need to perform the multiplication operation before addition.

First, let's calculate 8 multiplied by 385: 8 x 385 = 3080

Next, let's add 971, 21, and 3080 together: 971 + 21 + 3080 = 4072

So, the value of 971 + 21 + 8x385 is 4072.

(64+36)x723

To find the value of this expression, we can perform the addition operation before multiplication.

First, let's calculate 64 + 36: 64 + 36 = 100

Next, let's multiply 100 by 723: 100 x 723 = 72300

So, the value of (64+36)x723 is 72300.

85x(1000+100)

Again, we can apply the distributive property to this expression.

First, let's calculate 85 multiplied by 1000: 85 x 1000 = 85000

Next, let's calculate 85 multiplied by 100: 85 x 100 = 8500

Now, let's add the two results together: 85000 + 8500 = 93500

So, the value of 85x(1000+100) is 93500.
