00:00In the name of Allah, the most Gracious, the most Merciful.
00:13Peace be upon you, dear students and viewers.
00:15As you know, we have started a new standard level of logarithms.
00:20The books that I am teaching you are from FBISC, Federal Board of Intermediate and Secondary Education.
00:31This is chapter number 3.
00:33You can learn this core concept and apply it on any of the board's books.
00:39If you have any questions or queries regarding this subject,
00:43you can ask me in the comment section or in my mail.
00:49I will make a video on it for you.
00:51I will give you the link of all the videos that I have made before in the i button.
00:58You can go and watch it.
01:00The exercise that we will start today is 3.3.
01:06As I have told you before, this is a new standard.
01:09In this video, we will solve the first question of exercise 3.3.
01:17We will do the last part of the first question.
01:19Log 22 raised to power 1 by 3 divided by 5 raised to power 3.
01:28We have the numerator and denominator in this.
01:37First, we will apply the quotient rule.
01:42After that, we will use the power rule.
01:44Log 22 raised to power 1 by 3 divided by 5 raised to power 3 is equal to
01:49Log 22 raised to power 1 by 3 minus log 5 raised to power 3.
01:54Now, we have applied the quotient rule 1 by 3.
02:01Now, we will apply the power rule.
02:04We will multiply the exponent 1 by 3 into log 22 minus 3 into log 5.
02:14Now, we have the answer.
