——- is a cubic polynomial about X, the coefficient of its highest order term is - 4, the coefficient of its second order term is 3 / 2, the coefficient of its first order term is 0, and the constant term is - 1

It can be the cube of - 4x - 2 / the square of 3x - 1

If the coefficient of the cubic term is 1, the coefficient of the quadratic term is 2, and the constant term is - 2, then the polynomial is_____ ?__

X + 2x-2 condition is not enough to write a term

8+88+888+…… +888…… 8 (100 eights), what are the hundred digits of sum? Why?

From 8 + 88 + 888, the number of hundreds is 9 8 7 6 5 4 3 2 10 cycle, so when 100 is (100-2) / 10 = 9.8
The eighth number is 2.8 + 88 + 888 + +888…… Eight (100 eights), and the hundred digits of the sum are two

50 6 (6666 666) by 50 8's (88888 What is the remainder of the product of (8888) divided by 7?
Hello, I see your answer to this question, 1.50 111 111 = 48 1111 11*100+11
50 6 (6666 666) by 50 8's (88888 8888) and then divided by 7 is 6 * 1 * 4 * 4 = 96 divided by 7
I don't understand these two steps. Can you help me? Thank you

111111 (6 ones) is divided by 7 and 50 6 (6666 666) = 48 6 (6666 666) * 100 + 6666 = 7 * 9 + 350 8 (88888 8888) = 48 8 (88888 8888) * 100 + 8888 = 7 * 12 + 4, the last is 3 * 4 = 7 * 1 + 5 remainder ----- 5 prompt: (7a + x) (7b + y) = 49ab + 7 (a + b) + XY

How many liters is a liter of water

One liter equals one liter, one kilogram equals two pounds, and one meter equals three feet

50 6 (6666 666) by 50 8's (88888 The remainder of the product of (8888) divided by 7 is to find the remainder

6 divided by 7 makes 6, 8 divided by 7 makes 1,
And 50 111 111 divided by 7 looks like this
First you have to find six ones One is divisible by seven, so 48 ones are OK,
50 111 111 = 48 1111 11*100+11
So 50 11 The remainder of 11 divided by 7 is the remainder of 11 divided by 7,
50 6 (6666 666) by 50 8's (88888 The product of (8888) divided by 7 is the remainder
6 * 1 * 4 * 4 = the remainder of 96 divided by 7 is 5
The answer is 5!

How many liters of water is 0.2646 cubic meters?

12121… What is the remainder of 12 (200 bits) divided by 13?

The answer is 12
I won't tell you the method of proof, just a hint
12 / 13, more than 12;
1212 / 13 surplus 3
121212 / 13 more than 0; the key comes out, think about when you do division, more than 0 how you do next, think about it, oh, close to the answer
So every addition of three 12 remainders is 0
If there is only one 12 in a hundred, the answer is 12
It is also known that the number of two hundred twelve is 3
