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
77.6 is about twice the value of 38. So d8 must go into 776 2 times, 20 times, 200 times, etc. Changing that 77.6 number back to 776 must add one decimal place to 2 times, and it becomes 20 times.The actual times is about 20.42, so the estimate was pretty close.
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
