The value range of a that log2 is the bottom power of a is greater than log3 is the bottom power of 27 is

The value range of a that log2 is the bottom power of a is greater than log3 is the bottom power of 27 is


Solution steps:
because
log3^27=3,
therefore
If log2 ^ A is greater than log3 ^ 27, log2 ^ A is greater than log3 ^ 27
therefore
The value range of a is that a is greater than 8



The solution of equation log2 [(x power of 2 + 1) log (x power of 2 + 1 + 2) = 2 is______________ .


Let t = log2 (2 ^ x + 1), then log2 [2 ^ (x + 1) + 2] = log2 [2 (2 ^ x + 1)] = log2 (2) + log2 (2 ^ x + 1) = 1 + T, the original equation is t (1 + t) = 2, the solution is t = 1 or T = - 2, when t = 1, log2 (2 ^ x + 1) = 1, then 2 ^ x + 1 = 2, 2 ^ x = 1, x = 0; when t = - 2, log2 (2 ^ x + 1) = - 2, then 2 ^ x + 1 =



Verification: log2 (π) + log5 (π) > 2
Log 2 (π) is the logarithm of π with 2 as the base


The right way: first log5 (PI) / log2 (PI) = log5 (2) > log8 (2) = 1 / 3, then PI ^ (4) > 3 ^ 4 > 4 ^ 3, that is to say, PI ^ (4 / 3) > 4, then log2 (PI) + log5 (PI) = log2 (PI) * [1 + log5 (PI) / log2 (PI)] > (4 / 3) * log2 (PI) according to the above



(log5)^2+(log2)(log50)=?


(log5)^2 + (log50)(log2)(log5)^2 + (log(5*10))(log2)=(log5)^2 + (log5 + log10)(log2)=(log5)^2 + (log5 + 1)(log2)=(log5)^2 + (log5)(log2) + log2=(log5)(log5 + log2) + (log2)=(log5)(log10) + (log2)=(log...



Simplified evaluation: 1 / 3 (- 3ax & # 178; - ax + 3) - (- ax & # 178; - 1 / 2ax-1), where a = - 2, x = 3
First, simplify 1 / 3 (- 3ax & # 178; - ax + 3) - (- ax & # 178; - 1 / 2ax-1), and then bring in a = - 2, x = 3


"Mathematical answer group" for you to answer, I hope to help you
1/3(-3ax²-ax+3)-(-ax²-1/2ax-1)
= -ax²-ax/3+1+ax²+1/2ax+1
=ax/6 +2
= -2×3/6 +2
=-1+2
=1

The coordinates of two points a and B of triangle ABC are (- 6,0) (6,0), respectively. The product of the slopes of the lines where AC and BC are located is - 4 / 9,
How to find the trajectory equation of vertex C?
A. B coordinate should be the focus, that is (- C, 0) (C, 0) C = 6. But the equation I worked out according to the topic is x ^ 2 / 36 + y ^ 2 / 16 = 1, that is, a = 6, B = 4. It's obvious that there's something wrong with it. I hope someone can tell me what's wrong with it, or directly tell me the correct solution,
I know the method you are talking about. I used to calculate the answer according to this method. I just want to know, is this trajectory an ellipse? Are the two points a and B the focus? By the way, the second bit process seems to be wrong. The slope is k = Y / x, not X / y


As for the solution, it is not difficult: let the coordinates of points on the curve be (x, y), then we know y / (x + 6) * y / (X-6) = - 4 / 9 under certain conditions of slope product, so the equation is 9y ^ 2 + 4x ^ 2 = 144. Obviously, this is an ellipse, and the "sum of distances" from any point of the ellipse to two focal points is constant
