tinh tran man hinh 302^7
giup mik nha thank
Cho a,b>0 , a+b=1. Chung minh rang:
\(\frac{2}{ab}+\frac{3}{a^2+b^2}\)≥14.
Moi nguoi giai giup minh voi, mai kiem tra roi. Cam on truoc nha!
cho bieu thuc A=(x-√x/√-1+1):(x+√x/√x+1) (x≥0;x≠1)
a. tim x de bieu thuc A co nghia ? rut gon A?
b. tinh gia tri cua bieu thuc A tai x =7+4√3
lm giup mik nha
giup vs

Duong link day nhe
Giup minhk
so sanh \(\sqrt{5}+\sqrt{7}\) va 2\(\sqrt{6}\)
giai full giup minh nhe!thanks
Mong cac ban giup minh
tim so x khong am biet
\(\sqrt{X}< \sqrt{2}\)
\(\sqrt{X}< 3\)
M=(2-√3)(2+√3)
N=3+√3/√6+√2
P=2a+√ab-3b/2a-5√ab+3b
giai giup mik voi
giai phuong trinh sau:
\(x+\sqrt{x+\frac{1}{2}+\sqrt{x+\frac{1}{4}}+\frac{1}{4}}=2\)
m.m giup minh cau nay aj. thank m.n
