1. Make sure the numbers aren't imaginary.
(Imaginary numbers can't be real)
2. Irritational cannot be written as a fraction.
Soooo, you are correct! :)
Which of these numbers can be classified as both real and irrational?
a. 5.85
b. 63.4
c. square root 21
d. square root 36
Is the answer D?
7 answers
So the answer is 100000% D?
NO! 36 = 6^2, so sqrt(36) = 6, a rational number.
4^2 = 16 and 5^2 = 25
so 21 has no rational square root.
The answer is C
4^2 = 16 and 5^2 = 25
so 21 has no rational square root.
The answer is C
no sqrt 36 = 6
but what is sqrt 21 ?
but what is sqrt 21 ?
square root 21=4.582575695, so is the answer C? Because I do not understand what you are saying. C is the answer?
√21 is not 4.582575695
It is 4.582575695....
and is not a rational number
How many different ways do we have to say the answer is CCCCCCCC??????
