hello there this is the fastest paper of igcse and for this video iamp;#39;m going to do the answers for the questions related to logarithm okay this is the question number three and it is a 2016 question and you have a five parts question here okay so when they mention lg over here it represents lock with base of 10 all right so now we have now we are going to answer the questions okay these two we move up it becomes log x square minus width just copy and paste this x plus 10 over 2 all right when you have a minus here when you have a minus over here it means it is a divide so next step is log we divided with x plus 10 over 2 and this could be inverted to explain further for this is x square you divided by x plus 10 you divide it with two when they divide change to multiply this is will be inverted to x plus 10 okay now your answer will be this x square will multiply 2 and it become 2 x square over x plus 10 so this is the working that will be replaced over here so now your next step

In order to eliminate the log, which has a default base of 10, we will need to raise both sides of the equation as powers using the value of 10.
You can convert the log values to normal values by raising 10 to the power the log values (you want to convert). For instance if you have 0.30103 as the log value and want to get the normal value, you will have: 10^0.30103 and the result will be the normal value.
0:01 25:26 Now you might already see the answer but im going to go ahead and solve. It. Now we know that 2 toMoreNow you might already see the answer but im going to go ahead and solve. It. Now we know that 2 to the 4th power is 16..
2:06 6:25 Now we have the same bases. And they cancel. Out. And so log base 3 of 9 is the same thing as two.MoreNow we have the same bases. And they cancel. Out. And so log base 3 of 9 is the same thing as two. Okay one more. Easy. Example log base 4 of 64 again were going want to rewrite the big.
To do this, we just need to put x = ln(y) into exponential form. First, we need to recognize that ln(y) is a logarithm with base e, where e is an irrational number with an approximate value of 2.71828. ln(y) = log e (y). By the rule, we have that x = ln(y) is equivalent to y = e x.
To rid an equation of logarithms, raise both sides to the same exponent as the base of the logarithms.
Correct answer: In order to eliminate the log based ten, we will need to raise both sides as the exponents using the base of ten. The ten and log based ten will cancel, leaving just the power on the left side.
Lesson Summary. To review, we can undo logarithms by exponentiating. Just like we can multiply both sides of the equation by 2 to undo division, we can exponentiate both sides by 2, or by any number for that matter, turning x = y into bx = by.
