Solve for x over the real numbers:
8^x = 2

Take the logarithm base 8 of both sides:
Answer: |x = 1/3

2.5 percent

Looks like you dreamed this one up yourself!!. No solutions exist!.

2300(1.035)^x,

4,600 = 2,300 x 1.035^x

2 = 1.035^x take the log of both sides

x = Log(2) / Log(1.035)

x =20.15 years to double.

FOR HOW MANY QUARTERS OR YEARS??!!.

Not sure how not including "to acidify contents of a test tube" was necessary information in preforming the question asked. As an acid is being used I thought that was clear.

“Not sure how not including  . . .  was necessary information ...”

I need a babble translator to understand this. Acids have many uses, not just the ones I listed.

But, anyway, it just validates my comment about how giving you the solution is a waste of time. 

Hum . . . I didn’t know anuss was spelled as A**S. Are you sure this isn’t a foreign spelling? Maybe it uses letters unavailable in standard fonts.  You should learn how to spell “performing” correctly.  All the letter are available for that word. 

-6xy^2-(-3xy^2)= -3 xy^2

log7+log(n-2)=log6n             it is true that loga+logb=log(ab)

log(7(n-2))=log6n                   logx is one to one

7(n-2)=6n

7n-14=6n

n=14

why did you post 2 of the same silly questions?

I hate these stupid guests asking dumb questions!!!!!!

Let x=17$ initial cost.

After the discount x'=x-10%x=17$-1.7$=15.3$

After the tax: x''=x'+6%x'=15.3$+6% 15.3$=15.3$+0.918$=16.218$

The total price is x''=16.218$

log7 + log (n-2) = log (6n)      by a log property we can write

log [7 ( n - 2) ]  = log (6n)       the log bases are the same, so we can solve this

7(n - 2)   =   6n

7n - 14   = 6n          add 14 to both sides, subtract 6n from both sides

n  = 14

Up your a*s

Solve for n:
log(7) + log(n - 2) = log(6 n)

Subtract log(6 n) from both sides:
log(7) + log(n - 2) - log(6 n) = 0

log(7) + log(n - 2) - log(6 n) = log(7) + log(n - 2) + log(1/(6 n)) = log((7 (n - 2))/(6 n)):
log((7 (n - 2))/(6 n)) = 0

Cancel logarithms by taking exp of both sides:
(7 (n - 2))/(6 n) = 1

Multiply both sides by 6 n:
7 (n - 2) = 6 n

Expand out terms of the left hand side:
7 n - 14 = 6 n

Subtract 6 n - 14 from both sides:
Answer: |n = 14

184 = 2^3 * 23

Thanks for "wasting your time" and giving yet another childish response. By the way you should probably learn to spell A**S right asshat.

-4x+y=4 (1)             -4x+y=4          (1)

2x+2y=13 (2)             4x+4y=26        (3)    

We add equations 1 and 3  ,and we get :5y=30=>y=6

We replace y=6 to the equation 1: -4x+6=4=>4x=2=>x=1/2

Assuming it was possible to live on Mercury.......the period of revolution is 87.97 days

So.......assuming 365 days per year....and 11 -year-old  would be

11 *   365 / 87.97   ≈  45.6 years old  [ in " Mercury" years ]

Let's just simplify this :

( 20^3 x 20^2 x 20^1)  x  [ ( 20 x -20 x 20 )   x  (20 x  -20)  x  20 ]  =

( 20^6 )  x [  ( - 8000) x (  - 8000 ) ]   =  

20^6* (-8000)^2 =

4,096,000,000,000,000

Lift one of your leg up and move it forward and then do this with the other leg. Nice you just learned how to walk! Congrats!

cuz 1=1

-5x-2 *19=-12

-5x-38=-12

-5x=38-12

-5x=26

x=-26/5

Verification:-5*(-26/5)-2*19=26-38=-(38-26)=-12

1. Simplify sqrt108x^5y^8

I'm assuming that x and y are positive

√[ 108 x^5 y^8]  =  √[36 *3 * x^4 * x * y^8 ] =  6x^2y^4 √ [ 3x]

2. Simplify (sqrt3) - (sqrt2)/(sqrt3) + (sqrt2)

[ √3 - √2 ] / [ √3 + √2 ]       multiply top/bottom by √3 - √2

 ( [ √3 - √2 ] [ √3 - √2 ] ) / ( [ √3 + √2 ] [ √3 - √2 ] )   =

( 3 - 2√6 + 2 ) / ( 3  - 2)  =

[ 5 - 2√6 ] / 1  =

[ 5 - 2√6 ]

3. Rewrite 32^5/3 as a radical expression and then simplify

32^(5/3)   =   ³√[ 32^5] = ³√[ (2^5)^5]  =  ³√[ 2^25]   = 2^8* ³√2  = 256 3√2

The most important factor in suicide by jumping is height. Stone2 states that jumping from 150 feet (46 metres) or higher on land, and 250 feet (76 metres) or more on water, is 95% to 98% fatal. 150 feet/46 metres, equates to roughly 10 to 15 stories in a building, depending on the height of one story. 250 feet is the height of the Golden Gate Bridge in San Francisco.

In your previous post, you failed to include this part of the question

... to acidify contents of a test tube

While that is what I thought you wanted to know, I couldn’t be sure.  What I did know was anyone careless enough to post a question proofread with a half-assed wave of your whomper, probably doesn’t have the intelligence, education, or attitude to understand the answer.

Why should I or anyone else waste time on someone who needs his anuss debrided?
