38 = 2 x 19
Yes, you can write 38 as a product of prime factors. Since it is an even number, you can start by dividing 38 by 2. Your answer is 19. Since 2 and 19 are prime numbers, you are done. Prime factorization of 38 is: 2 X 19 = 38
To estimate the product of 726 and 5, we can round 726 to 700 and multiply it by 5. Multiplying 700 by 5 gives us 3500. Therefore, the estimate for 726 x 5 is 3500.
The solution to the factorization - the factors are 1, 2, 19, 38
Well, darling, a reasonable estimate for 776 divided by 38 would be around 20.4. Just divide the nearest hundreds place numbers, and you'll get pretty close to the actual answer. But hey, who's counting anyway? Just remember, math is like a recipe - sometimes you can eyeball it and still come out with a decent result.
round 38 to 40 and get 80 by multiplying. Then, do 38 x 2 and you’d have to round to get about the same answer.
The answer is 2,800. To estimate the product of 2 numbers, you round to the nearest ten or hundred. In this case, you would round 73 to 70, and 403 to 400, to make it easy to multiply. 70 x 400 = 2,800
There is no need to estimate: 38 - 12 = 38 - (10 + 2) = 38 - 10 - 2 = 28 - 2 = 26.
2*19 = 38
The product is 38
38 = 2 X 19
It is: 2*19 = 38
38 = 2 * 19
It is: 2 times 19 equals 38
38 = 2 x 19
2 x 19 = 38
19 and 2
