One square meter is the square of one meter, which is equivalent to a square with a side length of one meter,
Meters are units of length,
The two cannot be compared
However, square meters can also be regarded as the area of the product of width and length
The product of two thirds and a number is exactly equal to three fifths of 20
Let this number be X
2/3*x=20*3/5
x=18
The product of the multiplication of two factors is 143. The two prime numbers are () and ()
The product of multiplication of two factors is 143, and the two prime numbers are (11) and (13)
If and only if f (x) = logax-x + 2 (a > 0 and a ≠ 1) has two zeros______ ．
If the function f (x) = logax-x + 2 (a > 0, and a ≠ 1) has two zeros, that is, the image of the function y = logax and the line y = X-2 have two intersections, it is easy to know from the image that a > 1. It can be tested that when a > 1, the function f (x) = logax-x + 2 (a > 0, and a ≠ 1) has two zeros, and the function f (x) = log

It is known that the product of two natural numbers is 5766 and their greatest common divisor is 31
Use short division. If you can't write it, you can say it
The product of these two numbers is 5766. If 5766 is decomposed into prime factors, all prime factors of these two numbers should be included
5766=2*3*31*31
Remove the two greatest common divisor 31 (because both numbers have the prime factor of 31), and the remaining 2 and 3 are the unique prime factors of these two numbers
Then, these two numbers should be 31 * 2 = 62 and 31 * 3 = 93 respectively
Can the static friction be calculated by the formula F = UN?
In terms of friction, this formula can only be used when the object moves horizontally
For example, if you place a table horizontally, if you push 20n horizontally and don't push it, then the friction force is 20n. If you push 30n and he doesn't move, the friction force is 30n. If you push 40n and he moves, you can use the above formula to calculate. Maybe the friction force is 35n, then his friction force is 35n
22 * 7 / 33 = fraction * fraction = fraction
22*7/33=2/3*77/11=14/3
Note: there are multiple answers to "= fraction * fraction", such as = 7 / 11 * 22 / 3 = 11 / 3 * 14 / 11 =
Answer the Mathematical Olympiad questions of grade five in primary school (prime number and composite number)
Write out 10 continuous natural numbers (at least 20 kinds) that are all composite numbers. Thank you!
Want continuous natural numbers! Just list five
Let me help you to analyze this problem. We know that 10 consecutive natural numbers, even numbers must be combined numbers, so we only need to analyze 5 odd numbers
We also know that for the numbers 2, 3, 5, 7, 9, 11, 2 * 3 * 5 * 7 * 9 * 11 = 20790, which can be divided by the six numbers, then 20790 + 2 can be divided by 2, 20790 + 3 can be divided by 3 20790 + 11 is divisible by 11
So we can list such a group of numbers 20792 20793 20794 20795 20796 20797 20798 20799 20800 20801 20802. They are all combined numbers
