$n \times n \times n \times n \times n \times n \times n$ $nxxnxxnxxnxxnxxnxxn$

Explanation:

Assumption: The dot in n^3.n^4 means multiply

Have a look at https://socratic.org/help/symbols for formatting.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$n^{3} \to n \times n \times n$ $n^3->nxxnxxn$
$n^{4} \to n \times n \times n \times n$ $n^4->nxxnxxnxxn$

So multiplying these together gives

$n \times n \times n \times n \times n \times n \times n \leftarrow$ $nxxnxxnxxnxxnxxnxxn larr$ this is 7 n's

So

$n^{3} \times n^{4} = n^{3 + 4} = n^{7} = n \times n \times n \times n \times n \times n \times n$ $n^3xxn^4" "=" "n^(3+4)" "=n^7 =nxxnxxnxxnxxnxxnxxn$
