## How to calculate the Eighth root?

## What is the 8th root of 256?

The 8th root of 256 has exactly one real eighth root and has two additional complex 8th roots.

The eighth root of 256 is a number that multiply by itself 8 times to give us 256.

Dividing 256 by 2 gives us 128 which is equal to:

256 = 2 × (64 × 2)

= 2 × 2 (32 × 2)

= 2 × 2 × 2 × (16 × 2)

= 2 × 2 × 2 × 2× (8 × 2)

= 2 × 2 × 2 × 2 × 2 × (4 × 2)

= 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

The eighth root of 256 is 2 which is perfect 8th root.

## What is the 8th root of 6561?

The 8th root of 6561 has exactly one real eighth root and has two additional complex 8th roots.

The eighth root of 6561 is a number that multiply by itself 8 times to give us 6561.Adding the digits of 6561, we get 6 + 5 + 6 + 1 = 18, that mean is a multiple of 9 and 3, this tells us that 6561 is a multiple of 3.
