Question

Compare the equation √13/√8 and √7√5

Answer 1

Answer:

Step-by-step explanation:

Which is greater: 4√3 or 3√4?

Solution:

In order to compare two surds, they have to be similar i.e., they have to be surds of the same order.

4√3 is a surd of 4th order and 3√4 is a surd of 3rd order.

4√3 can be written as 31/4 and 3√4 as 41/3.

It is still not possible to compare. For this we need to take the LCM of the two orders and express them as surds of one order.

LCM of 3 and 4 is 12.

1/4 can be written as (1/4)*(3/3) = 3/12 AND 1/3 can be written as (1/3)*(4/4) = 4/12.

31/4 can be written as 33/12 41/3 can be written as 44/12.

33/12 = (33)1/12 = 12√27 44/12 = (44)1/12 = 12√256

Now, the comparison is between 12√27 and 12√256.

Clearly, 12√256 is greater as 256 > 27.

Therefore, 3√4 > 4√3

Not the correct answer but the way is given

Answer 2

Water is essential for life and for good health. The right to water is a part of the Right to Life under Article 21. Thus, it is an important responsibility of the government to provide water to everyone. However, at some places where the government fails to execute its responsibility, it is passed on to the private sector to fulfil it. There are few cases of private water supply in the world because

Most of the time, they carry out work that offers them profits.

Hence, we often see them supplying water through tankers or supplying drinking water in sealed bottles, which costs extra.

They provide water, but at a price that only some people are able to afford.

Thus, when the private companies increased the price of water, riots broke out in some places, which forced the government to withdraw the service from private hands.
