Please help, I am very confused on how to go about doing these two problems. 1. Traders often buy foreign currency in hope of making money when the currency's value changes. For example, on July 6, 2011, one U.S. dollar could purchase 0.6985 Euros and one Euro could purchase 1.3822 Canadian dollars....

I didn't mean multiply I just didn't know how to put the circle in between I wanted to compare the composite functions

Solve the exponential equation
3^(x^2-5x+3)=9^(x-4.5)

Please help show me how to solve this equation!
