Answer 1

Ответ:

Пошаговое объяснение:

26²-12²*3+175=419

6³-2*3³-1³=146

15²:(13²-124=5

8³:4²-2³=24

Answer 2

(26•26) - (12•12) * 3 + 175= 675 - 144 • 3+ 175 =675-432 + 175 = 243 +175= 68

(6•6•6) - 2 •(3•3•3) - 1 ( будет 1 потаму что 1•1•1=1) = 216 - 2 • 27-1 = 216- 54 -1=

Answer 3

Sure, let's solve each expression step-by-step:

1. 26² - 12² * 3 + 175

First, perform the operations inside the parentheses:

26² = 26 * 26 = 676 12² = 12 * 12 = 144

Now, substitute the values back into the expression:

676 - 144 * 3 + 175

Next, perform the multiplication:

144 * 3 = 432

Substitute the result back into the expression:

676 - 432 + 175

Now, perform the addition and subtraction:

676 - 432 = 244 244 + 175 = 419

So, the final result is: 419.

2. 6³ - 2 * 3³ - 1³

First, perform the exponentiation:

6³ = 6 * 6 * 6 = 216 3³ = 3 * 3 * 3 = 27 1³ = 1 * 1 * 1 = 1

Now, substitute the values back into the expression:

216 - 2 * 27 - 1

Next, perform the multiplication:

2 * 27 = 54

Substitute the result back into the expression:

216 - 54 - 1

Now, perform the subtraction:

216 - 54 = 162 162 - 1 = 161

So, the final result is: 161.

3. 15² : (13² - 124)

First, perform the operations inside the parentheses:

13² = 13 * 13 = 169

Now, perform the subtraction:

169 - 124 = 45

Now, substitute the result back into the expression:

15² / 45

Next, perform the division:

15² = 15 * 15 = 225

Now, perform the division:

225 / 45 = 5

So, the final result is: 5.

4. 8³ : 4² - 2³

First, perform the exponentiation:

8³ = 8 * 8 * 8 = 512 4² = 4 * 4 = 16 2³ = 2 * 2 * 2 = 8

Now, substitute the values back into the expression:

512 / 16 - 8

Next, perform the division:

512 / 16 = 32

Substitute the result back into the expression:

32 - 8

Now, perform the subtraction:

32 - 8 = 24

So, the final result is: 24.
