Log8 9 equals ah, log35 equals B, then LG2 equals

Log8 9 equals ah, log35 equals B, then LG2 equals

Change the bottom
lg9/lg8=a
lg5/lg3=b
Multiply to get
ab=2lg5/3lg2
Then 2lg5 = 3lg2 x ab
1=lg10=lg2x5=lg2 +lg5
2(1-lg2)=3lg2 X ab
lg2=2/(2+3ab)

It is known that log8 9 = a, log3 20 = B, and LG2 is represented by a and B

Log8 9 = lg9 / LG8 = 2lg3 / 3lg2 = a; log3 20 = LG20 / Lg3 = (1 + LG2) / Lg3 = B; from this, the binary linear equations are established, and the solution is LG2 = 2 / (3ab-2),

LG2 is a, Lg3 is B, and ab is log12 (5)

log12 5
=lg5/lg12
=(1-lg2)/(2lg2+lg3)
=(1-a)/(2a+b)

According to a certain law of the formula: 4 + 2, 5 + 8, 6 + 14, 7 + 20 So the 100th formula is______ ．

According to the above analysis, the 100th formula is: (4 + 99) + (2 + 99 × 6) = 103 + (2 + 594) = 103 + 596, so the answer is: 103 + 596

1. (2a) ^ 2-2 * (2a) + 1 = (2a-1) ^ 22. (2x) ^ 2 - 2 (2x) (2Y) + (2Y) ^ 2 = (2x-2y) ^ 2 = 4 (X-Y) ^ 23. (5x) ^ 2 + 2 (5x) (2Y) + (2Y) ^ 2 = (5x + 2Y) ^ 24. X ^ 2 - 2x (8a) + (8a) ^ 2 = (x-8a) ^ 25 x (x ^ 2-25) = x (x + 5) (X-5) 6

Use a number to remove 73, 79, 85, and the result is 1. What is the minimum number? What is the maximum number?

73, 79 and 85 are all reduced by 1 to get 72, 78 and 84. 72, 78 and 84 can be divided by 2 at least and 6 at most
So the minimum number is 2 and the maximum number is 6

X-3 / 4x = 60 * 2 / 3 to solve the equation
I'm in a hurry! I'm sorry. I'll offer a reward when I answer! Because I want to test, can't go too long!!

x-3/4x=60*2/3
1/4x=40
x=160
