In how many ways can the number 7126 be rearranged if no digit can be repeated?

To determine the number of ways, we need to consider that we have 4 different digits: 7, 1, 2, and 6. Since the first digit cannot be zero, we have 3 choices for the first position. Once we place a digit in the first position, we are left with 3 digits for the second position. Similarly, for the third position, we have 2 choices left, and for the last position, only 1 digit remains. Therefore, the number of ways to rearrange the digits is 3 × 3 × 2 × 1 = 18.

Question: If 7126 is divided by the sum of its digits, multiplied by the cube root of 7126, and then multiplied by 10, what is the result rounded to the nearest hundredth?

To find the result, we first add the digits of 7126: 7 + 1 + 2 + 6 = 16. Next, we find the cube root of 7126 ≈ 19.16. Now, we divide 7126 by (16 × 19.16) and multiply the quotient by 10. Therefore, (7126 ÷ (16 × 19.16)) × 10 ≈ 23.3333, rounded to the nearest hundredth, becomes 23.33.

What is the sum of the digits in the number 7126?

The sum of the digits in the number 7126 is 16.
