Răspuns:

Explicație pas cu pas:

1)  log₇35 + log₇9 - log₇45 = log₇(35·9/45) = log₇7 = 1

2) 3/3^log₃10 - 4/4^log₄5 + 6^log₆8/6 = ³⁾3/10 - ⁶⁾4/5 + ⁵⁾8/6 =

= (9-24+40)/30 = 25/30 = 5/6

3) log₂3 · log₃16 = log₂3 · log₂16/log₂3 = log₂2⁴ = 4

4) log₃^₁₎₂4 · log₂ 9¹⁽⁴ = (log₂4 / log₂3¹⁽²) · log₂ (3²)¹⁽⁴ =

= log₂2²·log₂3¹⁽² / log₂3¹⁽² = 2log₂2 = 2

5) ; 6) ; 7) ; 8) => in poza
