The greatest common divisor of 42 and 70 is______ The least common multiple is______ .

42 = 2 × 3 × 7, 70 = 2 × 5 × 7, so the greatest common divisor of 42 and 70 is 2 × 7 = 14, and the least common multiple is 2 × 7 × 3 × 5 = 210
The greatest common factor and the least common multiple of 42 and 75
Using the short division method: divide 42 and 75 into one and three at the same time, and they are 14 and 25 respectively. Let's see that 14 and 25 have common factors, and we find that they don't have any. The minimum common multiple is 3 ＾ 14 ＾ 25 = 2150, and the maximum common factor is 3
The greatest common factor and the least common multiple of 70 and 42 are ()
A. 7、140B. 2、126C. 14、210D. 14、140
70 = 7 × 2 × 5, 42 = 7 × 2 × 3, so the greatest common factor of 70 and 42 is 7 × 2 = 14, and the least common multiple is 7 × 2 × 5 × 3 = 210
A problem of plural
Find the complex Z satisfying | (Z + 1) / (Z-1) | = 1 and Z + (2 / z) ∈ R
Let z = x + Yi, (x, y ∈ R), then Z + 2 / z = x + Yi + 2 / (x + Yi) = x + 2x / (X & sup2; + Y & sup2;) + [y-2y / (X & sup2; + Y & sup2;)] I get y-2y / (X & sup2; + Y & sup2;) = 0 from Z + (2 / z) ∈ R. so y = 0 or X & sup2; + Y & sup2; = 2. If y = 0, then z = X. | (Z + 1) / (Z-1) = | (x + 1) / (x-1) | = 1, then x =

Ask: is it all plus s
Do you mean plural as singular?
the meeting involves ( )in the city
mathematics teachers
The plural form of mathematics is used as a singular noun
Who can tell me how to translate this sentence? And why add s after teacher? Can't mathematics teacher?
The question you mentioned is quite common in English. Now the explanation is as follows: mathematical is an adjective, mathematics is a noun form, and the plural form of mathematical adjective is a singular noun. There are many usages in English. Take two examples: good adjective, good goods noun, goods electronic
That's what mathematics is
There are two short forms: math and math
Mathematical is an adjective
Mathematics is noun mathematics
Mathematical is an adjective
Mathematics is a noun form
The plural form of an adjective is used as a singular noun
FOR EXAMPLE
good adj.
goods n.
The whole meaning of that question is
This meeting needs the participation of math teachers in the city
There must be more than one math teacher in the city
So teachers
Mathematics teachers is a specific noun
physics teachers
Chemistry teachers and so on
Otherwise, change to the form of noun + adjective
Chemical teachers is a bit of a teacher of chemical evolution
Mathematics is not a plural form, it is a single complex word.
