Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Cubes hide in prime factor triples.
A number is a perfect cube only when every prime factor appears a multiple of 3 times in its prime factorisation.
↳ To test or build a cube, count prime exponents in groups of three.
Two numbers, two names — don't mix them.
↳ In (x, y), x is the abscissa and y is the ordinate.
Four identities, endless questions.
↳ Recognising the pattern is faster than expanding every term.
A Class 8 CBSE half-yearly scope covering cubes and cube roots, coordinate geometry (plotting and reading points), factorisation by common factors, and algebraic identities. The focus is on multi-step problem solving — p…

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
A number is a perfect cube only when every prime in its prime factorisation has an exponent that is a multiple of which number?
Beginner3
A perfect cube is $n \times n \times n$, so every prime appears three times over — its exponent must be a multiple of 3.
Which of the following numbers is a perfect cube?
Beginner9261
$9261 = 3^3 \times 7^3 = 21^3$, so all exponents are multiples of 3. The others have primes with exponents not divisible by 3.
For the point $(-10, -7)$, what is the abscissa?
Beginner$-10$
The abscissa is the $x$-coordinate, which is $-10$ in the ordered pair $(-10, -7)$.
What is the first step when factorising any algebraic expression?
BeginnerPull out the HCF of coefficients and lowest powers of common variables
Factorisation always begins by removing the highest common factor — this is the step that makes the remaining expression manageable.
