Which expression can be used to approximate the expression below, for all positive numbers a, b, and x, where a ≠ 1 and b ≠ 1? log a× log b× / log b Baseline a log Subscript b Baseline a Over log Subscript b Baseline x EndFraction log Subscript a Baseline b Over log Subscript x Baseline b EndFraction log Subscript a Baseline x Over log Subscript b Baseline x EndFraction

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
