What is the pithy formula for pluralizing English nouns
The singular number changes into the plural number. The rules should be remembered. Generally, s is added. There are several special places at the end of / S / es. after ES, the letter O is added at the end. Most of them add S. two people have two dishes. Es is not separated. There are V and e before F, Fe and S. if there are no rules, you must remember them separately
Generally + es. Words ending with e directly + s, special cases to remember
1、 In general, add s directly
2、 Direct + s ending with s, x, SH, Ch
3、 Ending with consonant + y, change y to I + es. Vowel direct + s
4、 F, Fe is changed into V + es. Half of the leaves are yellow. His wife is cutting grain with a knife. A wolf comes out behind the shelf, just like a thief running for his life.? (including 9 words ending with F, Fe)

Life is an uncountable noun. Why are there plural forms
Life is like a journey, no matter what the destination, but the scene a
It's countable when it means one's life.
For example, their lives are equally precious as ours? Yeah. For example, life. OO, life is an abstract noun, isn't it? Yes, it means that life, life, life (in some way) is countable or uncountable. It means that a period of life experience and life is countable
It's countable when it means one's life.
For example, their lives are equally precious as ours?
Find the extremum of the following functions: 1) f '(x) = 6x ^ 2-x-2 2) f' (x) = 3x ^ 2-x ^ 3
1) By integrating f '(x) = 6x ^ 2-x-2, we get: F (x) = 3x & sup3; - X / 2-2x + B (the function is continuous in the domain R)
Let f '(x) = (2x + 1) (3x-2) = 0
X = - 1 / 2 or x = 3 / 2
Simple increment of x0 function
Zero
The results of two rational operations are still rational numbers. () the results of two irrational operations are still irrational numbers
The result of an irrational number and a rational number operation is still irrational!
The first question, for 1x1 = 1,1 + 1 = 2,1-1 = 0
The second question, wrong π - π = 0
Third question, wrong √ 2x √ 2 = 2
It's all self judgment,
The result of two rational operations is still rational. Then (√ 2) = 2
The result of two irrational operations is still irrational. (×) such as √ 2 * √ 2 = 2
The result of an irrational number and a rational number operation is still irrational. (×) such as 0 * π = 0, 0 / √ 3 = 0, e ^ 0 = 1, (√ 2) & # 178; = 2
It's all wrong. First, if you divide 1 by 7, you get an irrational number. And the second question is, root 7 is an irrational number, and the square of root 7 is 7, which is a rational number. Third question, (1 / 7) is an irrational number, 7 is a rational number, the multiplication of the two is 1, that is a rational number. So. All three questions are wrong
The known function f (x) = ax ^ 3 3x ^ 2-6ax-11, G (x) 3x ^ 2 6x
And f '(- 1) = 0
(1) Finding the value of a
f(x)=ax^3＋ 3x^2－6ax－11,g(x)3x^2 ＋6x＋ 12,
f'(x)=3ax^2+6x-6a
And f '(1) = 0
3a+6-6a=0
A=2
How can two rational numbers and two irrational numbers be calculated as positive integers with brackets
Rational number: 1, x + y (x > y) 2, XY (x, y are both positive or negative)
Irrational number: 1, A-B (a > b, and the number after the decimal point is the same) 2, a ^ 2
Add irrational numbers to get zero or integer
AB+[CD]
CD = 0. Positive or negative integer
Add or multiply irrational numbers,
The rational number is large and the rational number is small.
It is known that f (x) = (1 / 3x ^ 3) + (1 / 2) ax ^ 2 + 2x is an increasing function in the interval [- 1,1]
Find the set a composed of the values of real number a
F '(x) = x ^ 2 + ax + 2, because f (x) = (1 / 3x ^ 3) + (1 / 2) ax ^ 2 + 2x is an increasing function in the interval [- 1,1], so f' (x) is constant greater than 0 in the interval [- 1,1], that is, x ^ 2 + ax + 2 > 0 is constant in the interval [- 1,1]. When x > 0, that is, a > - (2 + x ^ 2) / X is constant in the interval [0,1], and - (2 + x ^ 2) / x = - (2 / x +
Can there be addition, subtraction, multiplication and division sign in irrational number? Can 1-radical sign 2
tolerable
Of course! As long as the number or formula in the root sign is greater than or equal to zero
Irrational numbers are not irrational & nbsp;
