a)tim GTLN cua P=x^2/x^4+x^2+1
b)cho 4x+5y=40, tinh GTLN cua Q=xy
tim gtln cua bt A=x^2/(x^4+x^2+1)
tim gtln cua M =x^2+y^2-x+6y+10
cho x>0,y>0, x+y=2012.
a, tim GTLN cua A= (2x^2+8xy+2y^2)/ (x^2+2xy+y^2)
b, tim GTNN cua B=(1+(2012/x))^2+(1+(2012/y))^2
cho 2 so x va y thoa man 3x+y=1
a) Tim GTNN cua bt M=3x^2+y^2
b) Tim GTLN cua bt N=x*y
cho √x + √y =4 tim gtln cua (√x +1 ) (√y + 2 )
tim GTLN cua \(\frac{x^2}{x^4+1}\)
Tim GTLN cua
a, A=4x-x^2+3
b,B=-x^2+6x-11
Tim gtln cua M=\(\frac{x}{\left(x+2018\right)^2}\)
