Translate the statements to algebraic expression
Represent the power with x;
So, the left hand side is
<em>Power of 10: </em>
<em />
<em>Times n: </em>
<em />
<em />
The right hand side is:
<em>0.1515 * power of 10: </em>
<em />
Equate the right hand side to the left:


Hence;
<em>The required expression is </em>
