Second answer is kinda weird... The equation is log1/2 (1/8) - log1/2 (32), and I don't know how to solve this one because it's in fractions not whole numbers, can someone help me show the steps how? Btw I only have the basic kindergarten calculators. (I know 1/2 is equal to 0.5, but I'm not sure if that would work?)

EDIT: Nevermind! I got the answer! Basically I just changed 1/2 to 0.5 and 1/8 to 0.125, I think I might solve this one!

Third, I'm also having trouble putting this in algebra or logarithmic terms, 8^x-3 = 16^x+3
