Best ResponseYou've already chosen the best response.1Property of Multiplying exponents of the same base: \[ a^{m} a^{n} = a^{m + n} \] 7 * 3 = 21 x * x^2 = x^(1+2) = x^3 y^2 * y^4 = y^(2+4) = y^6

Best ResponseYou've already chosen the best response.1Exponential notation is scientific notation, I believe. a * 10^b, where 1 <= a <= 9, and a,b are integers

Best ResponseYou've already chosen the best response.2...ok, I'm guessing that's the same as scientific. The first part has to be a number between 1 and 9, which in your case is 6.25. Because you have to multiply 6.25 by 100 to get 625, it's 6.25*100, or 6.25*10^2 in scientific notation.

Best ResponseYou've already chosen the best response.1oops, I should say, a is not integer! I forgot! D:

Best ResponseYou've already chosen the best response.2alternately, you can think of it as: from 6.25 to 625, you have to move the decimal back 2 places, so it's 10^2.

Best ResponseYou've already chosen the best response.2well, a can be an integer, but doesn't have to.

Best ResponseYou've already chosen the best response.2(a/b)^x = (a^x)/(b^x). You can apply this to that equation.
