Best ResponseYou've already chosen the best response.1is it \[ f(x) = 3(2)^{3^x} \]?

Best ResponseYou've already chosen the best response.1we can't do much with the first. the second can be written as \[ f(x)= 3(2^3)^x = 3\cdot 8^x\]

Best ResponseYou've already chosen the best response.0whats the difference between the two equations? @phi sorry my mum called me

Best ResponseYou've already chosen the best response.1the first one has \(3^x\) as the exponent. the second way has 3x as the exponent. the first way can't be simplified. the second way can be, using the rule \[ a^{bc}= (a^b)^c \]

Best ResponseYou've already chosen the best response.0(3x) is an exponent, they are both together and the same location/size... @phi

Best ResponseYou've already chosen the best response.1that means you can write the 2^(3x) as either \[ (2^x)^3 \] or \[ (2^3)^x\] the second way means \[ (2\cdot 2\cdot 2)^x \] or \[8^x\]

Best ResponseYou've already chosen the best response.1and we still have a 3 out front so you could write the expression 3 * 2^(3x) as 3*8^x

Best ResponseYou've already chosen the best response.1Does that match any of your options?
