Question

if log10 3=0.477 value of log10 9=?​

Answer 1

Answer:

0.954

log10 9 = log10 3^2 = 2log10 3= 2*0.477 = 0.954

Answer 2

Step-by-step explanation:

Given

$log_{10}(3) = 0.477$

we will calculate the value of

$log_{10}(9)$

$log_{10}(9) \\ log_{10}( {3}^{2} ) \\ \\ as \: we \: know \: that \\ \\ log( {m}^{n} ) = n log(m ) \\ log_{10}( {3}^{2} ) = 2 log_{10}(3) \\ 2 log_{10}(3) = 2 \times 0.477 \\ \\ = 0.954$

Answer is 0.954
