The factor of 16 is______ ; & nbsp; what is the greatest common factor of 10 and 15______ The least common multiple of them is______ .

The factor of 16 is______ ; & nbsp; what is the greatest common factor of 10 and 15______ The least common multiple of them is______ .

The factors of 16 are: 1, 2, 4, 8, 16; & nbsp; 10 = 2 × 5, 15 = 3 × 5, so the greatest common factor of 10 and 15 is: 5, and their least common multiple is: 2 × 3 × 5 = 30; so the answer is: 1, 2, 4, 8, 16, 5, 30
What is the greatest common factor and the least common multiple of 12 and 10
2 and 60, respectively
Is the plural of an uncountable noun itself, or is there no plural
The predicate must be singular without exception
But there are some collective nouns that need attention. For example, the predicate of people is plural
Uncountable nouns have no plural form, so they are called uncountable nouns
e.gbread——bread
water——water
flour——flour
There is no plural
Are uncountable nouns plural.
Given that the equation x ^ 2 + (4 + I) x + 4 + AI = 0 (a ∈ 5R) has real roots, find the value of a and its two roots
(a∈R)
Change to: x ^ 2 + 4x + 4 + I (x + a) = 0
If there is a real root, then both the real part and the imaginary part of the above formula are 0
X ^ 2 + 4x + 4 = 0, x = - 2
And X + a = 0, a = - x = 2
The original equation is: x ^ 2 + (4 + I) x + 4 + 2I = 0
The other root is (4 + 2I) / (- 2) = - 2-i
That is: a = 2, two are - 2, - 2-i
Is the plural of an uncountable noun itself or not?
No
Only countable nouns have plural forms. The plural of some countable nouns is itself
Uncountable nouns have no plural form, only countable nouns.
Given that a and B are two real roots of the equation x & sup2; - (2k + 1) x + 2K (K + 1) = 0, then the minimum value of a & sup2; + B & sup2; is? (quadratic)
Given that a and B are two real roots of the equation x & sup2; - (2k + 1) x + 2K (K + 1) = 0, then the minimum value of a & sup2; + B & sup2; is?
From the meaning of the title, we can get △≥ 0
a+b=(2k+1),ab=2k(k+1)=2k^2+2k
∴a^2+b^2=(a+b)^2-2ab
=4k^2+4k+1-4k^2-4k
=1
The plural of year is, isn't it an uncountable noun?
Year is a countable noun, including month, week, day, minute, second, etc., but it does not mean that two years is a countable noun, two years is a period of time, and time is uncountable, so your example should be changed to: two years is a long time
years
It's a countable noun. For example, two years, three years are two years, three years... Question: is time countable?
Z belongs to the complex number, Z-1 / Z + 1 is a pure imaginary number, find the minimum value of | Z ^ 2-z + 2 |
That is his pencil
Those are his pencils.
If Z is a complex number and w = 3Z + 2 / 3z-2 is a pure imaginary number, find | Z|

The writing of the title is not standard and ambiguous. I don't know how to solve it. It's better to edit it with the formula editor! ~
