Question

Please help, I am struggling with learning about this

Answer 1

Step-by-step explanation:

Change of Base formula: $log_ax=\frac{log_bx}{log_ba}$

b can be any number.

This formula is used because a lot of calculators can't calculate a logarithm with a base other than 10, so calculators don't show the bases, it is already assumed as base 10.

$log_725=\frac{log_{10}25}{log_{10}7}$

Type log(25) / log(7) to get: 1.6542

Pls let me know if u have any questions about logarithms, it helps me study!!
