Best ResponseYou've already chosen the best response.1that is simplified; in order to 'solve' we would have said x = some number

Best ResponseYou've already chosen the best response.0ok thanks but all the answers have either a 3 and an x or a 2 and a 3 and an x

Best ResponseYou've already chosen the best response.1maybe it more accurate to write it like this: cbrt(x^7) <=> x^2 cbrt(x) :)

Best ResponseYou've already chosen the best response.1^2 both sides to get: 9x +22 = x^2 0 = x^2 9x +22 0 = (x11)(x+2) x = 11 and 2 ; but we gotta dbl check because this way can have fake results: sqrt(9(11)+22) ?= 11 sqrt(99+22) ?= 11 sqrt(121) ?= 11 11 = 11 ; that ones good  sqrt(9(2) +22) = 2 .... aint no way that one works lol x = 11 is the answer

Best ResponseYou've already chosen the best response.1spose we have 9^x = 25 log(9^x) = log(25) x log(9) = log(25) x = log(25)/log(9) x = log9(25) its all good
