For this case we must rewrite the following expression:
[tex]7 * 7 * 7[/tex]
We have that by definition of multiplication of powers of the same base, we place the same base and add the exponents, example:
[tex]a ^ n * a ^ m = a ^{ n + m}[/tex]
So:
[tex]7 * 7 * 7 = 7 ^ {1 + 1 + 1} = 7 ^ 3[/tex]
Thus, the expression is rewritten as [tex]7 ^ 3[/tex], using exponents.
Answer:
[tex]7 * 7 * 7 = 7 ^ 3[/tex]
