a) given that 2^x = 1/[rt2] and 2^y = 4[rt2] find the exact value of x and the exact value of x b) given that 4^x = 8^(2-x) find the value of x c) given that3^x = 9^(y-1) show that x = 2y-2

I'll start you off Originally Posted by kls7162 a) given that 2^x = 1/[rt2] and 2^y = 4[rt2] find the exact value of x and the exact value of y take log to the base 2 of both sides: do the same thing here: b) given that 4^x = 8^(2-x) find the value of x note that and So we have now continue c) given that3^x = 9^(y-1) show that x = 2y-2 similarly here, now continue
