Math question: What is the sum of the square root of 2978 and the cube root of 2978, rounded to the nearest hundredth?

To find the sum, we calculate the square root of 2978 (approximately 54.57) and the cube root of 2978 (approximately 14.57). Summing these values yields 69.14 (rounded to the nearest hundredth), which is the solution.

Math question: If 2978 is divided by 7, how many times does 7 go into 2978?

To find out how many times 7 goes into 2978, we divide 2978 by 7. On dividing, we get 426 as the quotient. Therefore, 7 can go into 2978 exactly 426 times.

Math question: What is the largest prime factor of the number 2978?

To find the largest prime factor of 2978, we can begin by dividing it by the smallest prime number, 2. Since 2978 is even, it divides evenly by 2, resulting in 1489. Next, we proceed to divide 1489 by the smallest prime number greater than 2, 3. After division, we conclude that 1489 is not divisible by 3. Moving on, we divide 1489 by 5, which also does not yield an even division. Continuing this process, we divide by 7 and reach an even division, resulting in 7. Finally, we divide 7 by 7, which once again gives us 7. Hence, the largest prime factor of 2978 is 7.
