Best ResponseYou've already chosen the best response.066. false 67. true by distributive property. (1/6)*(x^2+3x) 68. false you're only multiplying the top by 5 it should be 5x^2/6 69. false you need to divide the first term by 3y as well 70. false 71.false same reasoning as 70. I can explain these if you want. 72.true x^28x+16=(x4)^2. then take the square root. 73.true ln(e^2)=2ln(e) 74.false e^(l+s)=(e^l)*(e^s)

Best ResponseYou've already chosen the best response.1wow lol ok lets start with 67...why did you multiply by 1/6?

Best ResponseYou've already chosen the best response.070 and 71: assume sqrt(x+y)=sqrt(x)+sqrt(y) square both sides x+y=x+2sqrt(x)*sqrt(y)+y this is not true unless x,y, or both are 0 so the equality cannot be true

Best ResponseYou've already chosen the best response.0dividing by 6 is the same as multiplying by (1/6)

Best ResponseYou've already chosen the best response.0dividing by anything is the same as multiplying by its inverse.

Best ResponseYou've already chosen the best response.1ok and well im still going down the list trying to see if i get it. are you sure 73 is true? b/isnt 2lne not the same thing as just 2 by itself?

Best ResponseYou've already chosen the best response.02lne=2. the equality is ln(e^2)=2 ln(e^2)=2ln(e)=2. ln(e)=1

Best ResponseYou've already chosen the best response.1oh ok for some reason i thought lne^2=1

Best ResponseYou've already chosen the best response.0no ln(e^2) means e to what power is e^2. so it is 2.

Best ResponseYou've already chosen the best response.1ok so if i said e^27 it would be 27 correct?

Best ResponseYou've already chosen the best response.0(e^l)^(s)=e^(l*s) not e^(l+s)

Best ResponseYou've already chosen the best response.0do you want me to explain why?

Best ResponseYou've already chosen the best response.1but i thought when you multiply exponents you add them like (x^5)(x^3)=x^8

Best ResponseYou've already chosen the best response.0yeah that is right. But you are multiplying e^l by itself s times. (e^l)^s=(e^l)*(e^l)*(e^l)*....*(e^l) < s times =e^(l+l+l+l....+l <s times)= e^(l*s)
