If x = 3 + 1, then the value of y = 2x Λ 5-4x Λ 4-x Λ 3-6x Λ 2-6 is

If x = 3 + 1, then the value of y = 2x Λ 5-4x Λ 4-x Λ 3-6x Λ 2-6 is

6√3

Calculation: 4x * x ^ 2 * x ^ 3 + x ^ 3 * x ^ 3-2x ^ 2 * x ^ 4
Just learned multiplication of the same base power, can't do t_ T. Seeking quick return

4X*X^2*X^3+X^3*X^3-2X^2*X^4
=4x^(1+2+3)+x^(3+3)-2x^(2+4)
=4x^6+x^6-2x^6
=3x^6;
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

I hope everyone can show his magic power

How many different five digit numbers can be made up of 5, 6, 7, 8 and 9 digital cards? What is the average of them?

5 * 4 * 3 * 2 * 1 = 120 different five digit numbers can be formed by 5, 6, 7, 8 and 9 digital cards,
Their average is 77777

There are five points below, and no three points are on the same line
If two points are connected into one line segment, how many line segments can they be connected into?
Change one word: one line a day

4 + 3 + 2 + 1 = 10

Nine cards are written with numbers 0, 1,..., 8 respectively. Take three of them to form a three digit number. If 6 can be used as 9, how many three digits can be formed?

Combinatorial problem
First of all, we should consider that the hundreds cannot be 0
So if there is 6. In this three digit number, then
If the hundred is six
C81*C71=8*7=56
If ten is six
C71*C71=49
If the one digit is 6
C71*C71=49
Because 69 is interchangeable
So the above results add up and multiply by 2
(56+49+49)*2=154*2=308
Consider the case of no 6
Then
C71*C71*C61=294
So the total number of three digits that can be made up is
308 + 294 = 602

There are six cards with 478125, five times of the six digits they make up is still a six digit, and they are also made up of these six digits
How many can you find out? Try it. Winter vacation assignment p27 in 2012 is also used to improve

142857×5=714285
148257×5=741285
174285×5=871425
174825×5=874125

How many different 4-digit numbers can be made up of digital cards 0, 6, 7, 8 and 9
We need formulas! We don't need equations!

First of all, there are four choices for thousand bits, because you can't choose 0. After you choose one thousand bit, there are still four choices for hundred bits, three choices for ten bits, and two choices for one bit, so 4 * 4 * 3 * 2 = 96 different 4-digit numbers. This is based on the principle of multiplication,

Use 7, 0, 8 and 6 to form different four digit numbers and compare their sizes
(1) Write two four digit numbers that read zero:______ 、_________ ；______

(1) Write two four digit numbers that read zero:__ 7086____ 、_____ 8076____ ；___ 7086___

The four numbers are composed of three digits and one digit respectively. The quotient should be the largest and the smallest
Urgent,

If the quotient is the largest, the three digit number should be 875, and the one digit number should be 3
If the quotient is the smallest, then on the contrary, choose 357 for three digits and 8 for one digit
