2015年9月28日 · There are a few different ways this can be seen. 1) Rationalize the denominator: #3/sqrt(3)=3/sqrt(3) * sqrt(3)/sqrt(3)= (3sqrt(3))/3=sqrt(3)#

2016年2月1日 · Since 3/sqrt(3) has a radical in its denominator, you must do a process known as rationalization. Rationalization is when you must multiply the whole fraction by another fraction where the numerator and denominator are sqrt(3). By doing so, you remove the radical, since sqrt(3) (1.7320508...) is irrational, that is, the decimal goes on forever without repeating. …

2015年10月1日 · 3 Anything times itself, is just the square. And the square of a square root is the number under the root, so sqrt(3) * sqrt(3) = 3

2016年4月26日 · arctan(sqrt(3)/3)= pi/6=30^@ Note that sqrt(3)/3 = 1/sqrt(3) Here is a standard trigonometric triangle with this ratio for the tan: Note that by definition the arctan function has a range of [0,pi) Trigonometry

2018年5月23日 · (2sqrt3)/3 You need to rationalize the denominator by multiplying it by: sqrt3/sqrt3 which equals 1 so it won't change the expression's value. 2/sqrt3 * sqrt3/sqrt3 (2sqrt3)/sqrt9 (2sqrt3)/3

2017年6月17日 · See explanation... "the square root of 3 divided by 2" could mean either of the following: sqrt(3/2)" " "the square root of: 3 divided by 2" sqrt(3)/2" " "the square root of 3, divided by 2". A square root of a number n is a number x, such that x^2=n. Every non-zero number actually has two square roots, which we call sqrt(n) and -sqrt(n). When we say "the" square …
