What is the value of determinant |1 7 49; 1 10 100; 1 18 324|?
Determinant |1 7 49; 1 10 100; 1 18 324| का मान क्या है?
Show answer and explanation
Correct Answer
D. 264
ExplanationStep 1: this is a Vandermonde determinant. Step 2: value is (b-a)(c-a)(c-b)=(10-7)(18-7)(18-10)=264. 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)=(10-7)(18-7)(18-10)=264। Step 3: tip: rows 1,x,x^2 हों तो pair differences multiply करें।
