If 5 / 7a ^ (K + m) B ^ m and a ^ (K + 2) B ^ 2 are of the same kind, and K is a non negative integer, then k = ()

If 5 / 7a ^ (K + m) B ^ m and a ^ (K + 2) B ^ 2 are of the same kind, and K is a non negative integer, then k = ()

k+m=k+2
m=2
So K is any number, if K is nonnegative, then k > 0 is OK

1. Only two nails are needed to fix a thin wooden strip on the wall. Its basis is (two points determine a straight line)
2. Use a matchstick to build a square in the following way. If you want to build n such squares in this way, you need (3N + 1) matches
3. The inverse of half is (- 1 / 2), the reciprocal is (2), and the absolute value is (1 / 2)
4. Wulingzhu has (10) vertices, (15) stripes and (7) faces
5. China's western region covers an area of 6400000 square kilometers, with scientific counting method (6.4 × 10 to the sixth power) of square kilometers

If the circumference of a rectangle is 44 cm and the length is 10 cm less than 3 times the width, the area of the rectangle is

If the width is x cm, the length is (3x - 10) cm
2x+2（3x-10)=44
The solution is x = 8
The length is 3 * 8-10 = 14 cm
The area is 14 * 8 = 112 square centimeters

If the product of (x's Square - MX = 1) * (X-2) does not contain the square term of X, find the value of M

(square of X - MX + 1) * (X-2)
=x³-2x²-mx²+2mx+x-2
=x³-(2+m)x²+2mx+x-2
∴2+m=0
∴m=-2

One factor of MX ^ 2 + 19x-14 is x + 7. Find m and another factor

Undetermined coefficient method
Let another factor be KX + B, where
（x+7）*（kx+b）＝mx^2+19x-14
That is, KX ^ 2 + (7K + b) x + 7b = MX ^ 2 + 19x-14
So, B = - 2, k = 3, M = 3
The other factor is 3x-2

The square of MX + 19x-14 has a factor X + 7. To find the value of M and another factor, don't use set

From - 14 = 7 × - 2
The other constant is - 2
From MX ^ 2 = x × MX, another unknown is MX
So MX ^ 2 + 19x-14 = (mx-2) (x + 7) = MX ^ 2 + (7m-2) x-14
So 7m-2 = 19
m=3
Another reason is (3x-2)

64 * (1 + x) square = 100 can you tell me how to do this kind of problem? Give me an example
64 * (1 + x) square = 100
Can you tell me how to do this kind of problem
For example,

64*（1+x）=100
1+x=100/64
1 + x = 25 / 16
X = 25 / 16-1
This is the answer, x = 9 out of 16
Example: for example, if 2x = 100, then x equals 100 divided by 2x equals 50

How to solve the problem that the square of 5x = x

5x²=x
5x²-x=0
x(5x-1)=0
X = 0 or 5x-1 = 0
The solution is x = 0 or x = 1 / 5

The square of X - the solution of 5x = 750?
I'm not going to tell you

Factorization
（x-30）(x+25)=0
x1=30,x2=-25

What is the solution of "64 + 16x = 2 (the square of x)"?

64 + 16x = 2 (square of x)
x²-8x-32=0
x1=[8+√(64+4*32)]/2=4+4√3
x2=[8-√(64+4*32)]/2=4-4√3
