2018年4月5日 · The sqrt0=0 The sqrt0 will be equal to 0 because 0^2=0. Think of sqrt0 meaning the square root of 0 objects, if you have no objects to square root, then the answer will be 0

2017年9月27日 · Definition of square root is what number multiplied by itself will give you the number within the square root function. 0 xx 0 = 0 Therefore sqrt(0) = 0

2017年12月12日 · Like any non-zero number #0.4# has two square roots. Since it is positive, both of those square roots are real and by convention the principal square root is the positive one, which we denote by #sqrt(0.4)#.

2018年4月15日 · My calculator says that sqrt(0.4) = 0.632455532. Perhaps the number being less than 1 is a problem with your method. So, let x = sqrt(.4)" " Then multiply both sides by 2. 2*x = 2*sqrt(0.4)" " Then square the 2 on the left while you bring it inside the radical. 2*x = sqrt(2^2*0.4) = sqrt(4*0.4) = sqrt(1.6)" " Then take the square root of 1.6 ...

2015年6月16日 · tan(x)+sqrt3=0 has two solutions: x_1 = -pi/3 x_2 = pi-pi/3 = (2pi)/3 The equation tan(x)+sqrt3=0 can be rewritten as tan(x)=-sqrt3 Knowing that tan(x) = sin(x)/cos(x ...

You can put this solution on YOUR website! 2cos(x)+sqrt(2)=0 cos(x) = sqrt(2)/2 x = pi/4, 3pi/4 (45 and 135 degrees)

2014年11月18日 · NO sqrt(0.4) is basically saying sqrt(40/100) 40 is not a perfect square, so the answer would be an irrational decimal number. So what square root equals 0.2? sqrt(0.04) If a number takes up 2 decimal points to the hundredths place, multiply it by 100 and the result is a perfect square, you can use this rule to find the square root of decimals.

2016年5月15日 · Note that #0.25# is the same as #25xx1/100#. Thus #sqrt(0.25)color(white)("dd")=color(white)("dd")sqrt(25xx1/100)color(white)("dd") =color(white)("dd") sqrt(25)/sqrt ...

There are two common ways to simplify radical expressions, depending on the denominator. Using the identities #\sqrt{a}^2=a# and #(a-b)(a+b)=a^2-b^2#, in fact, you can get rid of the roots at the denominator.

2015年9月15日 · 18/100 You know that 0.01 = 1/100" " and " "0.0064 = 64/10000 This means that you can write sqrt(0.01 ...
