Answer 3

1) 2³ = 2 × 2 × 2 = 8

To calculate 2 to the power of 3, we multiply 2 by itself three times. So, 2 multiplied by 2 is 4, and then 4 multiplied by 2 is 8. Therefore, 2³ is equal to 8.

2) 3² + 5² = 9 + 25 = 34

To calculate 3², we multiply 3 by itself, which gives us 9. Similarly, 5² is equal to 25. To find the sum of these two numbers, we add 9 and 25 together, resulting in 34.

3) 6² - 2⁴ = 36 - 16 = 20

To calculate 6², we multiply 6 by itself, which gives us 36. The term 2⁴ means 2 raised to the power of 4, which is equal to 2 × 2 × 2 × 2 = 16. Subtracting 16 from 36 gives us 20.

4) 20² - (10² + 9²) = 400 - (100 + 81) = 219

To calculate 20², we multiply 20 by itself, which gives us 400. The terms 10² and 9² mean 10 raised to the power of 2 and 9 raised to the power of 2, respectively. 10² is equal to 10 × 10 = 100, and 9² is equal to 9 × 9 = 81. Subtracting the sum of 100 and 81 from 400 gives us 219.

5) 6³ - 2 × 4³ - 1 = 216 - (2 × 64) - 1 = 216 - 128 - 1 = 87

To calculate 6³, we multiply 6 by itself three times, which gives us 216. The term 4³ means 4 raised to the power of 3, which is equal to 4 × 4 × 4 = 64. Multiplying 2 by 64 gives us 128. Finally, subtracting 128 and 1 from 216 gives us 87.
