Question

give proof with steps of logs​

Answer 1

$</p><p>\sf \rightarrow \quad {(2.9)}^{1 + log_{2.9} \: 10 } \\ \\ \sf \rightarrow \quad {(2.9)}^{1} \times {(2.9)}^{ log_{2.9} \: 10 } \\ \\ \sf \rightarrow \quad 2.9 \times 10 \qquad \bigg( \: \because \: x = {y}^{ log_{y} \: x } \bigg) \\ \\ \sf \rightarrow \quad 29 \\ \\ \sf Hence, \: Proved.</p><p>$
