Hi, we are given here some expressions here.
00:07
We are going to simplify that.
00:08
So we are going to use the law of exponents.
00:10
I will explain this and side by side i will just use the law of exponents which we are using here and i will solve it.
00:17
First of all we have k to the power 2 over 5 times k to the power 6 over 7.
00:28
This we have right.
00:30
So we have a law of exponents x to the power a times x to the power b.
00:34
We have same base in that case exponents get added right we get extra power a plus b so this will be k to the power 2 over 5 plus 6 over 7 this we have now we just solve this 2 over 5 plus 6 over 7 this rational expression we need to add here so what we can do here is multiply and divide this by 7.
00:59
Multiply and divide this by 5.
01:01
We get 14 over 35 plus 30 over 35.
01:07
So we have same denominator.
01:09
We can add numerator.
01:10
We have 14 plus 30 over 35.
01:15
That is giving 44 over 35.
01:20
So we get here 44 over 35...
