Answer 1

Ответ:

Пошаговое объяснение:

1) -4*(2^3)^1\3+23=-4*2+23=-8+23=15

2)3*(2^4)^3\4-23=3*2^3-23=3*8-23=24-23=1

3)4^2,5-4=(2^2)^5/2-4=2^5-4=32-4=28

4)-28*(2^3)^1/3-17=-28*2-17=-56-17=-73

5)13*(3^3)^2/3+26=13*3^2+26=13*9+26=117+26=143

Answer 2

To evaluate the given expressions, let's simplify each one step by step:

1. Expression: -4 * 8^(1/3) + 23

   • First, calculate the cube root of 8: 8^(1/3) = 2
   • Multiply -4 by 2: -4 * 2 = -8
   • Finally, add 23: -8 + 23 = 15 Therefore, the result is 15.

2. Expression: 3 * 16^(3/4) - 23

   • First, calculate the fourth root of 16: 16^(3/4) = 8
   • Multiply 3 by 8: 3 * 8 = 24
   • Finally, subtract 23: 24 - 23 = 1 Therefore, the result is 1.

3. Expression: 4 * 4^(1.5) - 4

   • Calculate the square root of 4: 4^(1.5) = 8
   • Multiply 4 by 8: 4 * 8 = 32
   • Finally, subtract 4: 32 - 4 = 28 Therefore, the result is 28.

4. Expression: -28 * 8^(1/3) - 17

   • Calculate the cube root of 8: 8^(1/3) = 2
   • Multiply -28 by 2: -28 * 2 = -56
   • Finally, subtract 17: -56 - 17 = -73 Therefore, the result is -73.

5. Expression: 13 * 27^(2/3) + 26

   • Calculate the cube root of 27: 27^(2/3) = 9
   • Multiply 13 by 9: 13 * 9 = 117
   • Finally, add 26: 117 + 26 = 143 Therefore, the result is 143.

The evaluated results for each expression are as follows:

1. -4 * 8^(1/3) + 23 = 15
2. 3 * 16^(3/4) - 23 = 1
3. 4 * 4^(1.5) - 4 = 28
4. -28 * 8^(1/3) - 17 = -73
5. 13 * 27^(2/3) + 26 = 143
