This topic is taught in Secondary 3 after introduction of Indices Law.
In solving indices equation involving the same base, one of the common techniques is by Substitution. But before you can do substitution, you need to apply indices law to 'break down' the equation. This process of breaking down is sometimes challenging for students. Knowing how to solve quadratic equation is also essential.
Sometimes, solving Indices Equation will also involve the concept of taking lg on both sides as well.
In the following example, you will Substitution and 'Breaking down' in action: [Read more...] about A-Math: Solving Indices Equation (Involving Common Base)
