Consider the given expression

$2^8$

Expand the expression:

It can be expanded as the product of eight 2's.

$2^8=2·2·2·2·2·2·2·2$

The second step is to start multiplication from the left side of the expanded expansion.

The multiplication from left to right s as follows,

$2^8=4·2·2·2·2·2·2$.

In the third step continue the multiplication to the left side.

Thus,$2^8=8·2·2·2·2·2$.

In the fourth step also continue the multiplication from left.

Thus,$2^8=16·2·2·2·2$.

In the fifth step also continue the multiplication from left.

Thus,$2^8=32·2·2·2$

Similarly in the pervious steps, continue the multiplication up to the final answer.

$$\begin{gathered} 32·2·2·2=64·2·2 \\ =128·2 \\ =256 \end{gathered}$$

Hence finally the simplified form of the given expression is 256.
