Sure! Let's evaluate each expression step by step.
23. 5 cubed:
To evaluate 5 cubed, we multiply 5 by itself three times.
5 cubed = 5 × 5 × 5 = 125
24. 4 squared:
To evaluate 4 squared, we multiply 4 by itself.
4 squared = 4 × 4 = 16
25. 9 squared:
To evaluate 9 squared, we multiply 9 by itself.
9 squared = 9 × 9 = 81
26. 8 cubed:
To evaluate 8 cubed, we multiply 8 by itself three times.
8 cubed = 8 × 8 × 8 = 512
So, the values of the given expressions are:
23. 5 cubed = 125
24. 4 squared = 16
25. 9 squared = 81
26. 8 cubed = 512
To evaluate each of the expressions, you need to raise the given numbers to the indicated powers. Here's how you can calculate each of them:
23. 5 cubed: To find 5 cubed, you need to multiply 5 by itself three times. Mathematically, it can be expressed as 5^3. So, the calculation would be: 5 * 5 * 5 = 125.
24. 4 squared: To find 4 squared, you need to multiply 4 by itself. Mathematically, it can be expressed as 4^2. So, the calculation would be: 4 * 4 = 16.
25. 9 squared: To find 9 squared, you need to multiply 9 by itself. Mathematically, it can be expressed as 9^2. So, the calculation would be: 9 * 9 = 81.
26. 8 cubed: To find 8 cubed, you need to multiply 8 by itself twice. Mathematically, it can be expressed as 8^3. So, the calculation would be: 8 * 8 * 8 = 512.
Therefore, the values for the given expressions are:
23. 5 cubed = 125
24. 4 squared = 16
25. 9 squared = 81
26. 8 cubed = 512
