Question

73^2-2*73*23+23______________26^2-24^2​

Answer 1

Ответ:

73²-2×73×23+23=5329-3358+23=1994

26²-24²=a²-b²=(a-b)×(a+b)=(26-24)×(26+24)=2×50=100

Answer 2

Let's solve the expression step by step:

73^2 - 27323 + 23

First, let's calculate 73^2: 73^2 = 73 * 73 = 5,329

Now, let's substitute that back into the expression: 5,329 - 27323 + 23

Next, let's calculate the multiplication: 27323 = 3,374

Substituting that back into the expression: 5,329 - 3,374 + 23

Now, let's simplify the addition and subtraction: 5,329 - 3,374 + 23 = 1,978

So the expression simplifies to 1,978.

Moving on to the second part of the expression:

26^2 - 24^2

Let's calculate the squares separately: 26^2 = 676 24^2 = 576

Now, let's substitute those values back into the expression: 676 - 576

Subtracting the two values: 676 - 576 = 100

Therefore, the second part of the expression simplifies to 100.

Combining both parts of the expression: 1,978 / 100 = 19.78

So the final result is approximately 19.78.
