a) log₂ 8 = x x = 3 , b0 2³ = 8 b) log₁₀ x = 2 <=> x = 10² = 100 c) log x 25 = 2 <=> x² = 25 <=> x = 5 d) log₆ √6 = x x = 1/2 e) log₇ x = 3 < => x = 7³ = 343 f) log x 32 = 5 <=> x⁵ = 32 <=> x = 2 ==================================
a) log(2) 8 =x x =3, bo 2^3 =8 b) log(10) x =2 x =100, bo 10^2 =100 c) log(x) 25 =2 x =5, bo 5^2 =25 d) log(6) V6 =x x =1/2, bo 6^(1/2) =V6 e) log(7) x =3 x =343 , bo 7^3 =343 f) log(x) 32 =5 x =2, bo 2^5 =32 (^ - do potęgi)
