: Equations, identities, and transformations of trigonometric expressions. Powers and Roots : Properties of -th degree roots and powers with rational exponents.

The official guide for the control works (tests) based on the is titled "Algebra and the Beginnings of Mathematical Analysis. Diadactic Materials for Grade 10" by Potapov and Shevkin. These materials provide multiple versions of control works designed specifically for the Nikolskii curriculum [1]. Structure of the Control Works

Before calculating, identify the fundamental theorem required. For example, if solving a trigonometric equation like , first use the Pythagorean identity to create a quadratic equation in terms of cosxcosine x Define the Domain (

) For logarithmic and fractional problems, always state the domain first. For

Based on the definition of a logarithm: Step 3: Solve for . Step 4: Check against domain. Since , the answer is valid. ✅ Final Answer The answer to the example problem is

The control works in this curriculum are typically divided into four variants (levels of difficulty) and cover the following key topics for Grade 10:

. This prevents "extraneous solutions" that could lead to a grade deduction.

: Solving equations and inequalities involving axa to the x-th power logaxlog base a of x
