What is the value of determinant |1 8 64; 1 11 121; 1 20 400|?
Determinant |1 8 64; 1 11 121; 1 20 400| का मान क्या है?
Show answer and explanation
Correct Answer
B. 324
ExplanationStep 1: this is a Vandermonde determinant. Step 2: value is (b-a)(c-a)(c-b)=(11-8)(20-8)(20-11)=324. Step 3: tip: for rows 1,x,x^2, multiply pairwise differences.
Step 1: यह Vandermonde determinant है। Step 2: value (b-a)(c-a)(c-b)=(11-8)(20-8)(20-11)=324। Step 3: tip: rows 1,x,x^2 हों तो pair differences multiply करें।
