There is a rule that states that a%5Em%2Aa%5En=a%5E%28m%2Bn%29. In your case we would solve as follows t%5E9%2At%5E7=t%5E%289%2B7%29=t%5E16.
A good manner of understanding how this works, is by looking at what the expression actually says:
t%5E9%2At%5E7=t%2At%2At%2At%2At%2At%2At%2At%2At+%2A+t%2At%2At%2At%2At%2At%2At+=+t%5E17, which also proves the general rule we used.
