Question

Can someone tell me how to solve this ?

Answer 1

2401 = (7)^4

so yr first answer is 4

Answer 2

Heya!

Here is yr answer.....


$1) \\ = > log_{7} \: 2401 \\ \\ = > log_{7} {7}^{4} \\ \\ = > 4 log_{7} \: 7 \\ \\ = > 4 \times 1 \\ \\ = > 1 \\ \\ \\ 2) \\ = > log_{0.5} \: 16 \\ \\ = > \frac{ log16 }{ log0.5 } \\ \\ = > - 4$


Hope it helps..
