In mathematics: if the exponential expression 4^3 is raised to a power then
you MUST use grouping symbols as (4^3)^2. The 2 and 3 are on the same
level.
On the other hand if the desire is to raise the first exponent to a power,
then you must NOT use grouping symbols and must write 4^3^2 in which case 3
is a superscript to 4 and 2 is a superscript to 3. So 3 is higher than 4
and 2 is higher than 3.
That's all I have to say about that.
