Remember P.E.M.D.A.S to be able to solve the equations. We'll be using the E (exponents) and M (Multipliction)
SOLVING...
1. 2.5 x 10^4
Solve Exponent... 10^4 = 10000
Multiply... 2.5 x 10000 = 25000
2. 3.4 x 10^4
Solve Exponent... 10^4 = 10000
Multiply... 3.4 x 10000 = 34000
25000 and 34000 are your answers
