Answer:
log₃(2z²)
Step-by-step explanation:
2(log₃8 + log₃z) - log₃(3⁴ - 7²)
= 2[log₃(2³) + log₃z] - log₃(81 - 49)
= 2(3log₃2 + log₃z) - log₃(32)
= 6log₃2 + 2log₃z - log₃(2⁵)
= 6log₃2 + 2log₃z - 5log₃2
= log₃2 + log₃(z²)
= log₃(2z²)
Answer:
log₃(2z²)
Step-by-step explanation:
2(log₃8 + log₃z) - log₃(3⁴ - 7²)
= 2[log₃(2³) + log₃z] - log₃(81 - 49)
= 2(3log₃2 + log₃z) - log₃(32)
= 6log₃2 + 2log₃z - log₃(2⁵)
= 6log₃2 + 2log₃z - 5log₃2
= log₃2 + log₃(z²)
= log₃(2z²)
