Question

va rog explicatimi va rog frumos

Answer 1

㏒₃ (x²+17) - ㏒₃(81) = ㏒₃ [(x²+17)/81]

Answer 2

[tex]\log _3\left(x^2+17\right)-\log _3\left(81\right) \\ \\ Calculam : \log _3\left(81\right) \\ \\ \log _3\left(81\right)=\log _3\left(3^4\right)=4\log _3\left(3\right)=4\cdot \:1=4 \\ \\ Deci : =\log _3\left(x^2+17\right)-4 [/tex]
