Question

Can I simplify; x=21/√3

Answer 1

firstly rationalize by multiplying by \[\sqrt{3}\] both numerator and denominator

Answer 2

you get \[21\sqrt{3}/3\]

Answer 3

You can't simplify it. The square root of 3 is not a multiple of 21.

Answer 4

to simplify rationalization is required

Answer 5

you get \[7\sqrt{3}\]

Answer 6

so my answer is that

Answer 7

Depends, are you in algebra?

Answer 8

If you are, you haven't learned rationalization. That means you can't simplify the fraction.

Answer 9

can that be an answer in finding exact value of x in a triangle that have degrees of 21 & 60

Answer 10

well you seem to have a problem with you triangle... and its non right angled... so the tan ratio doesn't work.... which was the original question I answered...

you you have angles of 21 and 60 the 3rd angle is 99 degrees so non right angled
