Answer 1

recapituleaza tot ce ai facut si vei lua o nata buna

Answer 2

III)

$\it \dfrac{log_5 x+ log_5 \sqrt x}{log_7 x+ log_7 \sqrt x} = \dfrac{log_5 x\sqrt x}{log_7 x \sqrt x} = \dfrac{log_5 x\sqrt x}{\dfrac{log_5 x \sqrt x}{log_57}} = log_5 x\sqrt x \cdot \dfrac{log_5 7}{log_5x \sqrt x} =log_5 7$
