Answer:
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
