For this case we must indicate an expression equivalent to:
[tex]9 ^ 7 * 9 ^ 3 =[/tex]
By definition we have to, to multiply powers of the same base, we place the same base and add the exponents. That is to say:
[tex]a ^ n * a ^ m = a ^ {n + m}[/tex]
Then, the given expression can be rewritten as:
[tex]9 ^ 7 * 9 ^ 3 = 9^{7 + 3}= 9^{10}[/tex]
ANswer:
[tex]9 ^ 7 * 9 ^ 3 = 9^{10}[/tex]
