hi! your videos helped me a lot with our current lessons and i'm very thankful for that. this means a lot to us students^^ have a good day and stay safe po! p.s. i hope you also make a video about answering word problems involving exponential expressions or conic sections, of course, only if you want to hehe
hello, can i ask po what if ung isang side lang ang fraction and it is also less than 1 but more than 0. for example: 3^x-4 < 1/27, will it be reversed po?
Hello Aleman :) Actually yung decision about reverse or retain the indicated inequality symbol ay naka depende lang sa base :) So if th eproblem is 3^x-4 < 1/27 , most probably ang base ay 3 so magiging x-4 < -3 ang set of exponents :) te answer is x
paano po yan, any fraction pwede nadin gawing whole number. example po ung 1/10 pwede sya irewrite as 10^-1 and ung 1/100 ay pwede irewrite as 10^-2. ano po and gagawin.. ireretain po ba talaga ang direction ng inequality symbol or hindi? PS. just asking for clarification, medyo nalilito din po kasi ako hahaha..
sir what if po fraction siya both side pero seems like hindi po siya pwede I raise sa iba pang power example po (1/27)^2x+1 < (1/243)^3x-2 what will be the process?
Hello NTC :) If that is the case , need na imodify or itransform ang dalawang Base mo (1/27) and (1/243) then iaaapply lang ang power rule for exponents , so magiging 1/3^3 ang 1/27 ----- then 1/3^5 naman ang 1/243 ---- bale ang new base mo ay 1/3 so need ireverse ang inequality symbol :) Then simplify lang (1/27)^2x+1 < (1/243)^3x-2 (1/3^3)^2x+1 < (1/3^5)^3x-2 (1/3)^3(2x+1) < (1/3)^5(3x-2) (power rule of exponents) 3(2x+1) > 5(3x-2) reverse the inequality symbol (bec base is less than 1) 6x+3 > 15x-10 Distributive Property, Then APE lang or Solve for the value of x 3 + 10 > 15x - 6x 13 > 9x Divide both side by 9 13/9 > x or x
