lg10+lg6/lg3=?


1+log2



What is LG6 minus Lg3,


lg6-lg3=lg(6÷3)=lg2



If 6 ^ a = 5, then | G25 / LG6 is equal to?


6 ^ a = 5, a = log (6,5) (6 is base, 5 is true) LG25 / LG6 = log (6,25) = log (6,5) = 2log (6,5) = 2A



Given Lg3 / LG10 = a, LG25 / LG6 = B, find LG45 / LG4
RTRT


It depends on the conditions
2lg5/(lg2+lg3)=b
lg3/(lg2+lg5)=a
As a system of equations about Lg3 and lg5, the solution containing LG2 is obtained. The solution can be obtained by taking (lg5 + 2lg3) / 2lg2 and eliminating LG2
If I'm right, it should be (4a + 3AB + b) / 2 (2-AB)



When using the method of undetermined coefficients to solve the differential equation y '' - 2Y '+ y = 2xe ^ 2x - (SiNx) ^ 2, what is the form of the special solution
thank you.


The solution of 2xexp (2x) + (SiNx) ^ 2 = 2xexp (2x) + 1 / 2 - (cos2x) / 2Y '' - 2Y '+ y = 0 is y = (C1 + c2x) exp (x) structure, which is different from 2xexp (2x) and (SiNx) ^ 2 = (1-cos2x) / 2. For 2xexp (2x), let the special solution Y1 = (AX + b) exp (2x) Y1' '- 2y1' + Y1 = (AX + B + 2a) exp (2x) = 2xexp (2x) get a = 2



It is known that there are six integer solutions of the inequality system x-a > 2,3-2x > 0 about X, then the value range of a is


From the meaning of the title

Positive sequence A0, A1, A2. An... Satisfies √ ana (n-2) - √ a (n-1) a (n-2) = 2A (n-1) (n ≥ 2), and A0 = A1 = 1, find the general term


If both sides of the original formula are divided by a (n-1) to get √ [ana (n-2) / a (n-1) ^ 2] - √ [a (n-2) / a (n-1)] = 2, let BN = √ [an / a (n-1)], then B1 = √ (A1 / A0) = 1, so BN / b (n-1) - 1 / b (n-1) = 2, that is, BN = 2B (n-1) + 1 (n ≥ 2), so BN + 1 = 2 [b (n-1) + 1], B1 + 1 = 2, so {BN + 1} is the first term of 2, and the common ratio is 2

1 / 4x-1 / 2 = 3 / 4 and 7x-5 / 4 = 3 / 8 I have nothing to share with you


1/4x-1/2=3/4 1/4x=1/2+3/4 1/4x=5/4 X=5 7x-5/4=3/8 7x=5/4+3/8 7x=13/8 X=13/56



A barrel of oil weighs 20 kg. When it is poured out of 13, it weighs 14 kg______ Kilogram


20 - (20-14) △ 13 = 20-6 △ 13 = 20-18 = 2 (kg); answer: the barrel weighs 2kg
