What is a coprime? It is known that the least common multiple of two coprime numbers is 77. What are the two coprime numbers_______

7 and 11
1 and 77
7 and 11
The least common multiple of two primes is 77, and the sum of the two primes is ()
77=7×11
The sum of these two primes is 18
Two different prime numbers, their least common multiple is 77, these two numbers are () and ()
The least common multiple of two different prime numbers is 77, which are (7) and (11) respectively
The quality factor of 77 is as follows
77=7×11
So these two numbers are 7 and 11 respectively
If you don't understand, please ask
Is √ ((1-I) ^ 2) equal to 1-I or I-1?
Equal to plus or minus 1-i
When I > 1, the sign changes and 1 > I remains unchanged
I want to ask how to write the plural of "family" and "brother"
Countable: Families
Uncountable: family
buddies
Plural of family: Families
The plural of buddies

Correct one point: family itself can be the plural of family, without change
Uncountable
A simple question about the plural
We know that the imaginary part of Z is a positive number, and | Z | = root sign 5. The square of Z + 2Z (the first horizontal) is a real number. If w = Z + AI. (a is less than or equal to 0 and greater than or equal to negative 3), we find the value range of | w |
Let z = x + Yi
|Z | = root 5, so x ^ 2 + y ^ 2 = 5
Z ^ 2 + 2Z is a real number, so x ^ 2 + y ^ 2 + 2xyi + 2x-2yi is a real number
So 2xy-2y = 0, so x = 1, so y ^ 2 = 4, because the imaginary part of Z is positive, so y = 2
Z = 1 + 2I, so w = 1 + 2I + AI A is less than or equal to 0, greater than or equal to negative 3, so 2 + A is less than or equal to 2, greater than or equal to - 1
|W | = root (1 + (2 + a) ^ 2) less than or equal to root 5 greater than or equal to root 3
Is family countable or uncountable? Does it mean both family and family? Is family its plural? For example, I have three families, three families, and family becomes the same plural?

A simple plural problem!
It is known that the two roots of the equation x & sup2; + X + P = 0 (P ∈ R) are X1 and x2. If | x1 | + | x2 | = 3, the value of P is obtained
When X1 and X2 are real numbers, we can get P = C = - 2 by thinking X1 * x2 = C / A; X1 + x2 = - B / A

When family is used as "family", it means plural. When family is used as subject, it means plural. When family is used as "family", it means singular. When family is used as "family", it means several families
Simple plural, tonight
Given that complex x ^ 2 + X-2 + (x ^ 2-3x + 2) I is a conjugate complex of 4-20i, find X
x^2+x-2=4
x^2-3x+2=20
X=-3
