2025年3月11日 · In this expert panel discussion, 4 top GMAT coaches - GMAT Ninja, Jeff Miller from TTP, Rida Shafiq from eGMAT, and Chris Gentry from Manhattan Prep. If (1/5)^m * (1/4)^18 = 1/ (2* (10)^35), then m = ? Be sure to select an answer first to save it in the Error Log before revealing the correct answer (OA)!

Correct answer is option 'A'. Can you explain this answer? If (1, 5, 35), (7, 5, 5), (1, λ, 7 and (2λ,1,2) are coplanar, then the ... To determine if the given points are coplanar, we can check if the determinant of a matrix formed by the coordinates of the points is equal to zero. Therefore, the only possible value of λ is 0.

Find step-by-step Linear algebra solutions and the answer to the textbook question If (1, 5, 35), (7, 5, 5), (1, λ, 7), and (2λ, 1, 2) are coplanar, then the sum of all possible values of λ is ..

JEE Main 2021: If (1,5,35),(7,5,5),(1, λ, 7) and (2 λ, 1,2) are coplanar, then the sum of all possible values of λ is (A) (39/5) (B) -(39/5) (C) (4

Step-1: Apply condition for four points are co-planer. Given four points are 1, 5, 35, 7, 5, 5, 1, λ, 7 and 2 λ, 1, 2. Step-2: Solve determinant by sarrus rule. Step-3: Use formula for sum of roots of quadratic equation - b a. Hence, correct answer is option (D). Q.

The correct answer is The points (1,5,35),(7,5,5),(1,λ,7) and (2λ,1,2) are coplanar⇒AB→AC→AD→=0⇒60−300λ−5−282λ−1−4−33=0⇒6[−33(λ−5)−112]−30[−(λ−5)(2λ−1)]=0⇒−33(λ−5)−112+5(λ−5)(2λ−1)=0⇒−33λ+165−112+1
