Answer:

$\sf\ your \: answer\implies: \overline{1}.17609$

Step-by-step explanation:

$\sf\huge \: \: log0.15 \\ \\ \\ \sf\ \implies: log15 \times {10}^{ - 2} \\ \\\sf\ \implies: - 2 + log(3 \times 5) \\ \\\sf\ \implies: - 2 + log3 + log5 \\ \\ \sf\ \implies: - 2 + 0.47712 + 0.69897 \\ \\ \sf\ \implies: - 2 + 1.17609 \\ \\ \sf\ \implies: \overline{1}.17609 \\ \\ \\ \\ \sf\ \bigstar \: log2 = 0 .30103 \\ \sf\ \bigstar \: log3 = 0.47712 \\ \sf\ \bigstar \: log5 = 0.69897$

Answer 2

log 0.15

==>log 15×10^-2

==>-2+log(3×5)

==>-2+log 3+ log 5

==>-2+0.47712+0.69897

==>-2+1.17609

==>bar 1.17609
