(The only alternative would be to define √2 as i√2 or to define √3 as i√3, which would be inconsistent with the definition of √1 as i rather than i) We have, thus, (√2)(√3) = ( i √2)( i √3) = i 2 (√2)(√3) = (√2)(√3) = √6, which is negative, whereas √6 is positive𝑟 𝑟 = √ 2 2 = √(−2√3) 2 22 = √124 √= 16 = 4 𝜃 tan𝜃 = ì ë = 2 − 2√3 = 2 −√3 ∙√3 √3 = 2√3 −6 = − √3 3 𝜃REF=30° 0 𝜃 is in Quadrant II 𝜃=150° Final answer 4cis150°Calculate 4 cos(4π/3) Determine quadrant Since our angle is greater than π and less than or equal to 3π/2 radians, it is located in Quadrant III
42√3 ( We cannot add this equation because in any number their is a root sign we cannot add it ) In equation a we take √3 and multiply by equation b (√3)× (2√3) Then we multiply √3 by 2 and √3 by √3 " in above equation" √3×2 = 2√3 √3×√3 = √9 But what's confuses me is, √3 √3 = 2√3 Then we add the 3 before the radical to get 4√3 how is that possible?The Galois Group Q (√2 √3) over Q Recall from the Galois Groups page that if is a field and is a field extension of then the Galois group of over is On the Automorphisms in the Galois Group of f (x) over K Permute the Roots of f page we proved that if is a field, is a field extension of , and then every permutes the roots of in
If one root of the equation x 2 px q = 0 is 2 √3, then the values of p and q are respectively If one root of the equation x 2 px q = 0 is 2 √3, then the values of 4 If two zeroes of the polynomial x 46x 326x 2 138x35 are 2 ±√3, find other zeroes Solution Since this is a polynomial equation of degree 4, hence there will be total 4 roots Let f(x) = x 46x 326x 2 138x35 Since 2 √3 and 2√3 are zeroes of given polynomial f(x) ∴ x−(2√3) x−(2√3) = 0 (x−2−√3)(x−2√3) = 0 On multiplying the above equation we get, Find the value of a and b if 5√3/72√3=ab√3 Answers Answer from josecito Stepbystep explanation find the value of a and b if 5√3/72√3=ab√3 Answer from Quest Ifound this on google "that means that the graph of a function with direct variation has these features it is a straight line because the slope is the ratio y

Rationalise the denominator of 1/√3√2 and hence evaluate by taking √2 = 1414 and √3 = 1732,up to three places of decimal asked in Class IX Maths by muskan15 (Answer The numbers √2 and √3 in the expression √2x√3 are surds because the roots of 2 and 3 can not be exactly determined They are irrational numbers Further, √2 and √3 are quadratic surds since the two surds are of the second order (The order of a surd is determined by the root symbolLet 0 = rcosθ and 2√3 = rsinθ By squaring and adding, we get (0) 2 (2√3) 2 = (rcosθ) 2 (rsinθ) 2 ⇒ 0(2√3) 2 = r 2 (cos 2 θ sin 2 θ) ⇒(2√3) 2 = r 2 ⇒ r = 2√3 ∴ cosθ = 0 and sinθ = 1 Since, θ lies in first quadrant, we have
This is the key to eliminating square roots from the denominator Note that (1 − √2 √3) is only a partial conjugate for (1 √2 √3) Multiplying these two expressions will eliminate terms in √2 but leave terms in √3 If we want to rationalise the denominator, we will also need to multiply by some expression of the form a b√3= x (x 2√3) √3(x 2√3) So we get, = (x √3) (x 2√3) Set your child up for success with Lido, book a class today!約5年前 √2+√3=√5ではありません! 根号の中身が同じでないと、計算してはダメなんですよ! 例えば、5√2+4√2なら、根号の中身が同じなんで=9√2 です! この回答にコメントする かなやん 約5年前 ルートの計算は、 ルートの中の数が、同じで
