Answer:[tex](-2)^{2}*7^{5}[/tex]
Step-by-step explanation:
You have to group all of the same one's together and however many there is, you add that number as the exponent.
There were 2 "(-2)" so that became [tex](-2)^{2}[/tex], and there were 5 "7" so that became [tex]7^{5}[/tex]. You keep the symbol and put it together which became [tex](-2)^{2}*7^{5}[/tex]
