- Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Equation 5x-7y+z=11, 6x-8y-z=15 and 3x+2y-6z=7, then the system is consistent and has infinitely many solutions.
Reasons (R): If D=0 then the 3 linear equations is consistent and has infinitely many solutions if D1 = D2 = D3=0.
In the light of the above Statements, choose the correct answer from the options given below : - If \(2^x\) = \(\sqrt[3]{64}\) ,then \(x^2 + x + 1\) = ?
