Which numbers would you choose to estimate the exact product of 2525?
I'd choose 20 and 30 and estimate the product at 600. The actual answer is 625.
If you wanted to find the largest possible product value of the sum of two numbers that equals the square root of 3 how would you do that?
The largest possible product of two numbers that add to give a greater number is half of that greater numbered, squared (where the two numbers are each half of the greater number). For the square root of 3, this would be ½ x √3 x ½ x √3 = ½ x ½ x 3 = ¼ x 3 = 0.75.
What is the least common multiple of two numbers that have no common factor greater than one?
It depends on what the numbers are. For example, if the prime numbers you were talking about were 3 and 7, the least common multiple would be 21. If your numbers were 2 and 3, it would be 6.
Estimate the product of 73 403?
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
What is a number greater than 50 with only 2 prime factors?
A number greater than 50 with only 2 prime factors would be a semiprime number. Semiprime numbers are products of exactly two prime numbers. An example of a semiprime number greater than 50 would be 77, which is the product of the prime numbers 7 and 11.
What could be the product of two even numbers and an odd number each of which is greater than 1 I don't understand this problem HELP?
It would have to be an even number greater than one as well.
Is the product of two numbers greater than either number?
Sometimes, sometimes not see 20,000 X 0 = 0 would be less. 20,000 X 1 =20,000 would be the same and 20,000 X 2 = 40,000 would be greater.
Explain whether it is easier to estimate the product 13.72 x 47.28 by using compatible numbers or by rounding each factor to the nearest whole number?
Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.
Estimate 199 over198 plus 35 over 17 indicating if the actual answer is greater than or less the estimate?
199 over 198 estimate = 1 actual answer would be greater than 1 35 over 17 estimate = 1 actual answer would be greater than 1
How do you know that the product of any two numbers greater than i must be a composite number?
Prime numbers have only two factors: one and themselves. By definition, your product would have more than that: one, the product and at least the two numbers that created the product. It has to be composite.
Estimate the product of 87 times 403?
To estimate the product of 87 times 403, you can round both numbers to the nearest tens or hundreds. Rounding 87 to 90 and 403 to 400, you get 90 x 400 = 36,000. This is a rough estimate of the product of 87 times 403.
If you mentally estimate the product of 313 and 489?
To mentally estimate the product of 313 and 489, you can round both numbers to the nearest hundred to simplify the calculation. 313 rounds to 300 and 489 rounds to 500. Multiply these rounded numbers together to get 300 x 500 = 150,000. This is a rough estimate of the product of 313 and 489.
