i cannot figure these out! i got the rest on my homework but these i dont get :/

how do you figure these problems step by step?

1. (logbase2(5)+logbasse2(3))*logbase15(4)

2. 1/logbase4(18) + 1/(2logbase6(3)+logbase6(2)) + 5/logbase3(18)

3. a=log2 b=log3 c=log5 and d=log7

express log(75*sqrroot2/98)^-2

4. (log7)(base3(20))(log3)(logbase7(5))/1-log2

any help appreciated!! these i just dont get!

thanks

I just can't figure out how to solve these few problems :/ please help? 10 points to the best explanation, please and thanks so much.

1) what mass of LiOH is required to react exactly with 15.0 mL of 1.8 M of H2SO4 soln?

2) a 2.18 g sample of an unknown diprotic acid is to tested to the 2nd equivalence point using 38.5 mL of a 2.118 M NaOH soln. 2NaOH + H2A --> Na2A + 2H2O

what is the molar mass of the acid?

3) an 85 g sample of Ca(OH)2 is dissolved in enough water to make 150.0 L of a solution. How many mL of this solution must be diluted with water to make 1.000 L of 0.00010 M Ca(OH)2?

I have no idea how to do this math problem, any help would be great!

My parents are extremely strict about my grades. Im a freshman in high school, and the quarter ends in 3 days. I have straight A's except for one B in math. i tried to bring it up, but theres no way i can since the grades close so soon. how can i tell my parents this?

how do you factor this? i cant figure it out..

My parents never listen to a thing i say, like when were trying to have a discussion. When we disagree about something, they always start to shout and say "i don't want to hear it, go to your room" or they threaten taking things away from me (like my phone, tv, etc) so i do what they say... but when they are actually wrong about the argument, they still wont listen, and this can be extremely frustrating. How can i get them to listen to what i have to say?
