24,26, &28 worked by Emily Johnson I got the same answers! Gr8 job Checked by Ellen Barth

36. ln (x^2 / y^3) ^ .5 = ln (x^1 / y^1.5) = **lnx - 1.5 ln y** 38. ln x- ln sqrt (x^2 + 1) = **ln x - .5 ln (x^2 + 1)** 40. ln sqrt(x^2) + ln sqrt(x + 2) = **.5 ln x^2 +.5 ln (x+2)** Done by: Blake Schreiber

looks good, I got the same answers checked by Jose Castellanos

62. ln(x^2-1)x^3 67. y=2 68. y=1/3 I was supposed to check, but no one has done it yet. Jennifer Hassell Sorry im late, ive been trying to update for the past 2 hours but my video card on my main comp died so it keeps blue screening so i had to wait for my mom to get home to use her laptop, i got the same answers 67. log (3) 9=x 3^x=9 x=2 68. log (6) cube root 6 6^x = cube root 6 x= 1/3 - Alex Dubois

69. y= 6.8 70. y= -3 71. 2^y= -4 cannot be done because of negative 72. 4^y= -16 cannot be done because of negative - done by Brooke Wiggins Done by: Alyssa Johnson I got the same thing! Checked by: Amy Finkelstein


 * 1) 77-80 worked by: Alyssa Sturgis

If that isn't a 1.5 and it's a 15, then these look good. Checked by Mady Smith


 * 81 and 82.**
 * I was supposed to check but it was never posted.**
 * Done by: Courtney Venable**


 * 1) 85) False; because f(x)=ln(x) and ln(0) does not equal 0. ln(1)=0
 * 2) 86) False; because f(1)=ln(1) and ln(1)=0
 * 3) 87) True; because f(ax)=f(a)+f(x) and a>0 and x>0, just like f(a/x)= f(a)-f(x)
 * 4) 88) False; because f(x-2) would equal f(x/2) not f(x)-f(2)


 * 1) 85-88 Done by Emma McRae

I agree with Emma! Checked By: Frances Dannenbrink

89)False, because the square root of f(x) is not the same thing as half of f(x); instead, f(the square root of x)= 1/2f(x) 90)False, because f(u) cannot equal 2f(v) if v is the larger number 91) True, because when 0 <x<1 in the equation f(x) the resultant number is always negative

I agree but I put 3 points on each graph -Matt Bogaert p.s. Giraffes rule
