Solve 1. log16x=3/2 2.logx81 = 3 3. Log21/8 = x thanks

Solve 1. log16x=3/2 2.logx81 = 3 3. Log21/8 = x thanks

solve 1)log24+2log28=x 2)log5(x+2)-log5 7 = 2log53 thanks this site helps a lot!

1) 2x =4 3√8 2) 5x=76 3) log31/27=x 4)23x-1=30 thanks it's much appreciated!

use the properties of logarithms to expand the logarithmic expression wherever possible evaluate logarithmic expressions ln((x+4)/(x2-16)5)(4/5)

i have been stuck on this problem lately

If (x1,y1) and (x2,y2) are the solutions of system of eqn log225(x) + log64(y) = 4, log(x)225 - log(y)64 = 1, find the value of log30(x1y1x2y2).

Use the change-of-base theorem to find each logarithm: log3.1481

show the equation to find the answer as well

the question contains logarithms and I don't know how to solve them. Can you please help explain this?

Log8(x3) A. Log8(3x) B. 3Log8(x) C. 3+Log8(x) D. Log3(8x) E. Log(x3) F. None of the above.

Log9(*squareroot*Q) A. 2Log9(Q) B. Log9(Q) C. 1/2Log2(Q) D. 1/2+Log9(Q) E. 1/2Log9(Q) F. None of the above.

The amount of carbon-14 present in a paint after t years is given by y=y0e-0.00012t. The paint contains 37% of its carbon-14. How old are the paintings?

ln(exR6) A. xe+6ln(R) B. e+R6 C. x+6ln(R) D. x+ln(6R) E. 1+6ln(R) F. None of the above.

From what I can guess, I can us the log property to bring the exponent -x in front of the 9 and make it -xLog9=Log3 (?)

log(y) / log(x) + log(z) / log(y) + log(t)/ log(z) =8.x^2.t Ican't find x Can you help me , please ? Thanks

Log4 (x^4) sqrt y

I don't understand where to go from here. How do I get the t's to equal the rest?
