S1 : Logarithm of a number x is defined for all negative values of x. S2 : Logarithm of 1 to the base x (where x>1) = 0
S1 is true, S2 is false
S1 : 13231400 is a non terminating decimal. S2 : A number pq where p and q are co-primes is terminating if q is of the form 2n.3m where n and m are non-negative integers.
The solution for the equations c1x + b1y + a1 = 0 and c2x + b2y + a2 = 0 is
S1 : x = (b1a2–b2a1)(c1b2−c2b1)
S2 : y = (c1a2–c2a1)(a1b2−a2b1)
In the given figure, ABCD is a parallelogram and PD is parallel to QC.
S1 : △APD ≅ △BQC
S2 : ar(△APD) + ar(PBCD) = ar(△BQC) + ar(CDPB)
S2 : area(△APD) + area(PBCD) = area(△BQC) + area(CDPB)
