Induction Inequality Proof: 2^n greater than n^3

[@WebDevAnjali]

am i the only one who literally can't do induction problems no matter what? my little brain just can't understand this doesn't matter how good the explanation is

feel you

[@chrisdiner7170]

These are really tough. It takes a while to wrap your brain around this. I can get through most of it, but still having trouble finishing the problem.

@@chrisdiner7170 i didn't study maths in highschool nor in college now solving such problems gives me a little heart ach 😂😂 only i know how I'm suffering through my master's degree in computer application where maths n algorithm analysis is my biggest pain 😂😂😂

[@taniyayadav5940]

Sir as third last value is completely greater than of the fourth last then also we need to give both greater than and equals to sign only greater than is not enough?

The beautiful of learning how to use reverse CLT. Break up like terms and compare.

[@alexandertownsend3291]

What is reverse CLT?

[@mrheng562]

@@alexandertownsend3291 , breaking up 3x to be 2x + x, CLT means collecting like terms. 😂😂😂

[@alexandertownsend3291]

@@mrheng562 Oh that makes sense I have just never seen anyone call it CLT before, I had only seen combining like terms. Thanks for the clarification.

Lol When I think of CLT, I think of the central limit theorem

Omg THANK YOU I was so confused about PMI

a little confused on how you put 2 next to k^3....😅

[@chakibboumi3522]

he multiplied both sides of the inequality by 2

[@Trazom488]

@@chakibboumi3522no he didn’t? He used basic exponent laws, 2^k+1 is the same as 2x2^k.

[@ashimbasnet6568]

how do you if it is 4^n >n^3. n in N i try to expand but there won't be enough for natural number

[@edoardobaima1872]

UoL midterm uh?

[@asimami3061]

Can't we solve it by putting the whole equation on one side other equation on other side?

[@ansazeem1234]

Just a clarification, can't we just say that since 2^k is greater than k^3, 2^k*2 will also be greater than k^3*2

[@brendanmccann5695]

WOW!!!

Sir... I am have zero background in mathematics.. Now i still try to learn math, because some condition make me to do that. I want to ask you how you organizing your math notes (because math have many different subject) i'm very confusing with it.. Please reply my problem T_T

[@alexandertownsend3291]

How far are you in math?

[@Ardanputratama]

@@alexandertownsend3291 I don't know the topic in english language,. I think im on algebra topic

[@alexandertownsend3291]

@@Ardanputratama Math is just as much about language as it is about numbers. If you struggle with English that can make learning math from sources in English tougher. My advice would be to either find math books in a language you feel more comfortable with, or build up your English language skills. Look up pre algwbra textbooks and if those seem too easy, look up algebra 1 textbooks. Don't feel bad English is a tough language even for native speakers.
