Question 3 simplify

Ques 1: 7.85

Ques 2: both and are rational.

Ques 3: 0.9

Step-by-step explanation:

Ques 1:

Solving the , we get 7.8485.

Rounding off to nearest hundredth, we see that next digit is 8, so we increase the previous digit by 1.

So, the answer to nearest hundredth is 7.85.

Ques 2:

and to be checked  whether they are rational or irrational.

We know that is equal to 4.

= -4 which is a rational value.

Let us solve now.

Which is a rational value.

So, both are rational.

Ques 3:

Simplify

0.81 can be written as in rational form.

Now, taking the square root, we need to take the square root for both Numerator and Denominator and then we can divide to get the desired square root.

So, the answers are:

Ques 1: 7.85

Ques 2: both and are rational.

Ques 3: 0.9

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
