Moving forward in our Number System series, this video dives into the fundamental concept of Power and Indices.
Many students use these terms daily, but do you know the formal mathematical definitions? In this "Concept Capsule," we break down:
The Definition: If a number p is multiplied by itself n times, it is called the nth power of p
Base vs. Index: Learn why in the expression 5
12
, 5 is the Base and 12 is the Index of the Power
Practical Examples: We look at how to represent 3×3 as the second power of 3, and 3×3×3×3×3 as the fifth power of 3
Coming Up Next: Stay tuned for the next video where we use these concepts to solve high-level competitive exam problems, such as finding the unit digit of large powers like 234
178
