Question

(90+510:30)*(80:4*5)в столбик

Answer 1

(90+17)×(20×5)
107×100
10700

Answer 2

To solve the given expression in column format, we'll break it down step by step:

Copy code
   90+510:30
×  80:4*5

Let's start with the first line:

yamlCopy code
   90 + 510 : 30

To evaluate this expression, we'll perform the division first:

scssCopy code
   90 + (510 ÷ 30)

The division gives us the result of 17, so the expression becomes:

Copy code
   90 + 17

Adding these numbers gives us the final result of 107.

Moving on to the second line:

Copy code
×  80:4*5

We'll perform the multiplication and division from left to right:

scssCopy code
× (80 ÷ 4) × 5

Dividing 80 by 4 gives us 20:

Copy code
× 20 × 5

Multiplying 20 by 5 gives us the final result of 100.

Therefore, the complete expression:

yamlCopy code
   90 + 510 : 30
×  80 : 4 × 5

Evaluates to:

Copy code
107
× 100

To calculate this multiplication, we multiply 107 by 100:

Copy code
10700

So, the result of the expression (90+510:30)(80:45) is 10,700.
