2nd and 3rd one pleaseeeee

2nd and 3rd one pleaseeeee EXERCISE questions. Each 4 5 log + 3 log I •is (b) log 3 (d) none of Z 49 'IS — log .(c) _ is 3 • log (d)

H i, 2 n d : \frac{\log 49 \sqrt{7} + \log 25 \sqrt{5} - \log 4 \sqrt{2}}{\log 17.5} = \frac{\log (49 \sqrt{7} \times 25 \sqrt{5}) - \log 4 \sqrt{2}}{\log 17.5} = \frac{\log \frac{(7^{2} \times 7^{\frac{1}{2}} \times 5^{2} \times 5^{\frac{1}{2}})}{2^{2} \times 2^{\frac{1}{2}}}}{\log 17.5} = \frac{\log \frac{{(7 \times 5)}^{\frac{3}{2}}}{2^{\frac{3}{2}}}}{\log 17.5} = \frac{\log {(\frac{7 \times 5}{2})}^{\frac{3}{2}}}{\log 17.5} = \frac{\log {(\frac{35}{2})}^{\frac{3}{2}}}{\log 17.5} = \frac{\frac{3}{2} \log {(\frac{35}{2})}^{}}{\log 17.5} = \frac{\frac{3}{2} \log 17.5}{\log 17.5} = \frac{3}{2}

Please post single query in a thread
