What is the quintic power of (a-b) and the quartic power of (B-A) and the third power of (a-b)?
And then there is X2N + 3 = xn times (what to fill in) = the fourth power of X (what to fill in)
Square of negative x + fourth power of y = (square of negative x + y) (what to fill in)
The cube of (x squared by x times the third power of X, m of Y) = what to fill in?
There are also 6N power of 4A - 10a3n power + (what to fill in?) =What do you want to fill in Square of

The fifth power of (a-b), the fourth power of (B-A) and the third power of (a-b)
=The fifth power of (a-b) the fourth power of (a-b) the third power of (a-b)
=The 12th power of (a-b)
And then there is X2N + 3 = xn times (the N + 3 power of x) = the fourth power of X (the 2N-1 power of x)
Square of negative x + fourth power of y = (square of negative x + y) (x + Y & sup2;)
The cube of (x squared by x times the third power of X, Y M) = the 18th power of X, the 3M power of Y

If (M + 1 power of a, N + 2 power of B) (2n-1 power of a, 2n power of B) = quintic power of a, then M + n

[a ^ (M + 1) B ^ (n + 2)] [a ^ (2n-1) B ^ (2n)] = a ^ 5B ^ 3, then find m + n
a^(m+2n)b^(3n+2)=a^5b^3
m+2n=5,3n+2=3
m=13/3,n=1/3
m+n =13/3+1/3=14/3

Calculate 1234 + 2341 + 3412 + 4123=______ ．

1234 + 2341 + 3412 + 4123, = (1111 + 123) + (2222 + 119) + (3333 + 79) + (4444-321), = 1111 + 2222 + 3333 + 4444 + (123 + 119 + 79-321), = 1111 + 2222 + 3333 + 4444, = 1111 × (1 + 2 + 3 + 4), = 1111 × 10, = 11110

If the parabola = (m-1) x ^ 2 + 2mx + m + 3 is located above the X axis, then the value range of M is ()

The parabola y = (m-1) x & # 178; + 2mx + m + 3 is located above the x-axis. Firstly, the opening of M-1 > 0 m > 1 must be upward, otherwise it will not conform to the meaning of the problem. Secondly, the minimum value (4ac-b ^ 2) / 4ac must be greater than 0 (4ac-b ^ 2) / 4ac = (2m-3) / (m-1) (M + 3) > 0, then: - 33 / 2m value range: (3 / 2, + ∞)

Proof: the product of four consecutive integers plus 1 is the square of an integer

Let the four consecutive integers be n-1, N, N + 1, N + 2, then (n-1) n (n + 1) (n + 2) + 1, = [(n-1) (n + 2)] [n (n + 1)] + 1 = (N2 + n-2) (N2 + n) + 1 = (N2 + n) 2-2 (N2 + n) + 1 = (N2 + n-1) 2. Therefore, the product of four consecutive integers plus 1 is the square of an integer

If 4x-3y = 0, the value of 4x − 5y4x + 5Y is ()

Properties of determinant of linear algebraic square matrix
Please prove the property of determinant of square matrix
A. If B is a square matrix, then the determinant of the product of AB is equal to the product of the determinant of a and B

Let d = [a, O] be a partitioned matrix
[-E B]
det(D)=detAdetB
After elementary transformation, the process of D [a, AB] transformation is to construct AB from the original position of O
It's not easy to narrate. It's easy for you to find the rules yourself
det(D)=det(AB)
So det (AB) = detadetb

What's the quotient of subtracting 3 / 7 of 35 from 25 by 1 / 3

30
3 / 7 of 35 is 15,
25 minus 15 = 10
10 divided by 1 / 3 is equal to multiplying 3 by 30
