Sagot :

Answer:

1.404

Step-by-step explanation:

Given:

[tex]\log_43 \approx 0.792[/tex]

[tex]\log_421 \approx 2.196[/tex]

[tex]\log_421 =\log_4(3 \times 7)=\log_43+\log_47[/tex]

[tex]\implies 2.196\approx 0.792+\log_47[/tex]

[tex]\implies \log_47 \approx 2.196-0.792[/tex]

[tex]\implies \log_47 \approx 1.404[/tex]
