What is the value of non-zero integer R?
STATEMENT (1)- \(R^3\) = \(R^R\)
R = 1 satisfy the equation \(R^3\) = \(R^R\)
R = 3 satisfy the equation \(R^3\)= \(R^R\)
we cant get definite value of R
so, INSUFFICIENT
STATEMENT (2)- |\(R^R\)| = 1
R = 1 satisfy the equation |\(R^R\)| = 1
R = -1 satisfy the equation |\(R^R\)| = 1
we cant get definite value of R
so, INSUFFICIENT
combining both statements
we know \(R^3\)= \(R^R\) and |\(R^R\)| = 1
R = 1 satifies both equations \(R^3\) = \(R^R\) and |\(R^R\)| = 1
R = -1 satifies both equations \(R^3\)= \(R^R\) and |\(R^R\)| = 1
we cant get definite value of R
so, INSUFFICIENT
