Mathematics A = 0.8 ^ - 2.2, B = 3 ^ - 0.7, C = 1.25 ^ 1.3

a=0.8^(-2)=(5/4)^2
b=3^(-0.7)=(1/3)^0.7
c=1.25^1.3=(5/4)^1.3
For a, C, C is obvious

What is a homogeneous polynomial of first degree? For example, what is a singular matrix?
What are homogeneous polynomials and singular matrices?

The so-called homogeneous is to homogeneous meaning, after the merger of similar terms, the degree of all polynomials are the same
For example, x-2y 3Z is homogeneous of first order; 3x ￣ 2 + y ￣ 2-8z ￣ 2 + xy-2yz is homogeneous of second order
For example, the square of x plus 2 times the square of XY plus 3 times the square of Y, so that all the quadratic terms are homogeneous, so it is a quadratic homogeneous, and the homogeneous polynomial is similar
Singular matrix is a matrix whose determinant is equal to 0, a term of linear algebra

What is the term and degree of a polynomial

Let's say the quadratic power of 2x, then the number of terms is 2x and the degree is 2

Hello, how to check the degree of a polynomial

The degree of a polynomial is to add up the degree of the unknown and take the degree of the term with the largest number of times. For example, the degree of 3x & # 178; y + 2x & # 178; = 0x is 2, the degree of Y is 1, (2 + 1 = 3, this is the degree of 3x & # 178; y. the latter degree is less than 3x & # 178; y, that is to say, the degree of this polynomial is the term of degree 3)

-The coefficient of the square of 5 π AB is () polynomial, and the square of X - 2x + 3 is () degree () term

Two three

G (x) = e ^ x (x ≤ 0) LNX (x ≥ 0) g [g (x)]

X0 = g [g (x)] = ln (e ^ x) = x
0

Given that f (x) = ax LNX, X belongs to (0, e], G (x) = LNX / x, where e is a natural number, a = 1, we prove that f (x) > G (x) + 1 / 2
(2) Let H (x) = f (x) - G (x) - 1 / 2 = x-lnx-lnx / X-1 / 2
h′(x)=(x²-x+lnx-1)/x²
Let H (x) = x & sup2; - x + lnx-1
Then h ′ (x) = 2x-1 + 1 / x = (2x & sup2; - x + 1) / x > 0
We know that h (1) = 0
So when 0

I'll give you my answer. I think of the above one for the first time, but I'm not going to give it to you if it's a little troublesome
First, you should ask
G (x) = LNX / x, we get the maximum g (x) max = 1 / E when x = E
So the maximum value on the right side of the sign is 1 / E + 1 / 2

Given the absolute value of X + 1 + 2y-5 = 0, then x + 2Y=

From the meaning of the title:
x+1=0
2y-5=0
The solution is: x = - 1; y = 5 / 2
x+2y
=-1 + 2 × 5 / 2
=-1+5
