Simplification: (log4 3 + log8 3) (log3 2 + log9 2) - log1 2 4 root number 32
log4 3 + log8 3) (log3 2 + log9 2) - log1 2 4 root number 32
log2^6+log2^6)(log3^2+log3^4)-log2^(-4)4√2
2*6log2)(6log3)-log2 (-4)2 (5 2)12(log2)(6log3)-log2 (-3 2)12(log2)(6log3)+3 2log2y=log1 2 (2x-1) domain under the root number.
y=√log1/2^(2x-1)
log1/2^(2x-1) ≥0
log1/2^(2x-1) ≥log1
1/2^(2x-1) ≥1
2^(2x-1) ≤1=2^0
2x-1≤0
x 1 2 Good luck.

log(a n) (b m)=(m n)loga b,loga b+loga c=loga (bc),loga b*logb a=1 basic common aa. Simplify(log(2 2) 3+log(2 3) 3)(log3 2+log(3 3) 2)-log(2 -1) (2*32) 2)=(5log2 3)(4log3 2)+6log2 2=26. It's a basic question when it's annoying to type on a mobile phone, and it's not going to be a liberal arts study.

Square the known and expand it to the 2y power of x + 2 + x to the -2y power.
So the answer is 2 times the root number 2-4

log2[2^(3/2)]≈log2(
log9(25)=log3(5) log3[3^(3/2)]≈log3(
log9(25)< 3/2 =68.Let 2 x=t
then y=t 2-3t+3=(t-3 2) 2+3 4 x [1,7].
2≤t≤128
then its value range is [1,16003].

-a + 1/(a+b)
If you want to know the specific process, you can ask me.

Note: The second part is the X power of multiplying A up and down!

Multiply a x up and down at the same time, and then simplify it to get the result.

1+a^-x)/2(1-a^-x)
1+1/a^x)/2(1-1/a^x)
1/a^x(a^x+1))/2(1/a^x(a^x-1)(1+a^x)/2(a^x-1)
In fact, it is to convert a -x into 1 a x and then divide and simplify.

Let y=2 x, the original equation becomes y-1 y=2, i.e., y-2y-1=0, and we get.
y=2^x=(2±√8)/2=1±√2
But when y=1-2<0, the formula is obviously meaningless.
So y=2 x=1+ 2
i.e. x = 2 (1 + 2).
If you are satisfied, welcome to adopt, thank you.
If you have any questions, please feel free to ask.
First of all, let's talk about the idea, 56 = 2*2*2*7, so only log42 2 and log42 7 are required >>>More
1.(1) Add left and subtract right, so choose
2) a≠0, =1+4=5>0, 2 intersections. >>>More
Solution: According to the topic.
It can be solved by the difference method. >>>More
y=sin²x+2sinxcosx+3cos²x1+sin2x+2cos²x
