Question

Jak obliczyć nastepujący logarytm

ile będzie x wynosić?

Answer 1

3 do potegi x= 3³/243

3 do potegi x=3³/(3⁵) do potegi ¼

3 do potegi x=3³/3 do potegi ⁵/₄

3 do potegi x= 3 do potegi ⁷/₄

 

x=7/4

Answer 2

          3^3                          3^3

=log3---------------= log3 ---------- = log3 3^7/4=7/4

        (3^5)^1/4                  3^5/4

 

 

bo 3^x=3^7/4; ^potęga

       x=7/4
