NCERT MCQ Solutions for Class 8 Maths Ganita Prakash Chapter 2 Power Play

Class 8 Ganita Prakash Chapter 2 covers various important concepts related to exponents and powers. The MCQs usually test your understanding of exponent laws such as multiplication, division and raising a power to another power. You will also find questions on converting large numbers into standard form using scientific notation. Some questions ask you to simplify expressions like 2³ × 2⁴ or (3²)³. There are also tricky ones based on zero or negative exponents. These MCQs are helpful because they strengthen your speed and accuracy in applying laws of exponents. They also teach you how to break down complex expressions into smaller parts. If you practice them regularly, you’ll get better at solving similar questions during school exams and other competitive tests. They build both confidence and clarity.

Scientific notation helps in expressing very large or very small numbers in a compact form. MCQs on this topic usually ask you to convert numbers like 0.00053 or 8700000 into standard form, using powers of 10. To prepare for these questions, understand how to shift the decimal point and count the digits carefully. Practice converting both directions—from number to scientific form and vice versa. These MCQs are important because they teach you to deal with real-world quantities, such as distance to stars or sizes of atoms, which are often written in scientific notation. Learning through MCQs helps avoid silly mistakes and improves your number sense. Regular practice will also train your mind to quickly estimate values and apply logic—both important in higher-level mathematics and science subjects.

Negative exponents often confuse students at first, but they follow a simple rule: a⁻ⁿ = 1/aⁿ. MCQs based on negative powers help you get comfortable with this idea. These questions usually ask you to simplify expressions like 5⁻² or 10⁻³ or sometimes combine them with other exponent laws. Practicing these MCQs is important because it removes the fear of negative numbers in powers. It also teaches you how to simplify expressions that look big but actually become small when evaluated. Many real-life formulas, especially in physics and chemistry, use negative exponents to represent tiny values. Solving such MCQs regularly builds accuracy, confidence and fluency. It helps you master the chapter quickly and prepares you for exams where quick decision-making is needed.

Some MCQs combine more than one rule of exponents in a single question. For example, you may be asked to simplify (2³ × 2⁴) ÷ 2² or (5²)³. These require you to recall and apply multiple laws like the product of powers and power of a power. Solving such questions improves your logical thinking because you must follow the correct order of operations. Practicing mixed MCQs trains you to solve problems in steps and avoid skipping important parts. These questions help sharpen your mind and are very useful in timed exams where both accuracy and speed matter. Over time, you’ll begin recognizing patterns and solving them almost instantly. That’s the power of regular MCQ practice—it builds your math muscle step-by-step.

Regular practice of MCQs boosts your understanding of concepts like exponent rules, powers of numbers, scientific notation and simplification techniques. Unlike long-form questions, MCQs test your precision and speed. They prepare you for school assessments, Olympiads and entrance exams by improving your ability to choose the correct answer from similar-looking options. Practicing MCQs also helps you develop confidence and reduces silly mistakes. You begin to understand where you’re going wrong and can fix those gaps. Over time, this focused practice builds strong mathematical reasoning. Chapter 2 is especially important because powers and exponents are used in algebra, geometry and science too. MCQs make Class 8 Maths Ganita Prakash Chapter 2 easier to master and more enjoyable to revise. They are a quick and smart way to test your learning.
