1. Well, , so we can write our fraction this way:
2. You (should) know this: and this: . Now let's use the formulae for our exercise:
(ln 68)/13 - Wolfram|Alpha
Hope I helped. ^^
So i have some exercises i simply just can not wrap my head around, they are not hard but for some reason i cannot understand them.
Been doing some tests for school and it shows me the correct results in the end if i get it wrong.
(x+4)/(9x+36) , the result is 1/9 if any1 can make me understand how it's made i would appreciate it.
(6logx^2 + 6log1/x), i answered x^4/x^3 but the correct one is x^6, and i dont get it how.
(e^8x)(e^5x)=68, this one i tried doing it with loge=68 and simplify the final result by 40 but it doesen't get me the correct answer.(0.3246)
I realise this is preaty easy but i just need some help understanding it.
