Question

2 log 5 + log 8 - 1/2 log 4

Answer 1

= > 2 log 5 + log 8 - 1 / 2 log 4


From the properties of log,


= > log 5² + log 8 - log 4½


= > log 5 + log 8 - log √4


= > log 5 + log 8 - log 2



From the properties of log ,


$= > \dfrac{25 \times 8}{2} \\ \\ \\ \\ = > 25 \times 4$



= > 100




$\underline{ \text{ Hence, value of 2 log 5 + log 8 - 1/2 log 4 is 100 \: }}$
