Question

( left[begin{array}{ll}a & 0 0 & aend{array}right]=a I_{2} )
( b A=left[begin{array}{cc}0 & b -b & 0end{array}right]=left[begin{array}{ccc}a & b -b & aend{array}right] )
( a^{2}=b^{2}-(1) )
( a=b )

# If A = ar 4)2 = A , then - To 1-10 (A) a = b = V2 (B) a = b = 1/2 (C) a = b = 13 (D) a = b = 1/53 - ( N) is equal to -
