2³ is called the _____________ form of 8.

The correct answer is: Index

To find the relation between 2³ and 8

The index form of a number is that number written as an exponential expression, or a single number raised to another number.

8 = 2 × 2 × 2
= 2³

Here, 2 is the base and 3 is the index / exponent.

So, 2^3 is the index form of 8.
