Hury up,I wait for you
Don't forget to make my new friend
Tính nhanh: 751 x 68 + 751 x 32
751 x 68 + 751 x 32
= 751 x (68 +32)
= 751 x 100
= 75100.
tính nhanh : 751 x 25 + 751 x 75 + 200
751x25+751x75+200
=721x(25+75)+200
=721x100+200
=72100+200
=72300
= 751.(25+75)+200
=751.100+200
=75100+200
=75300

Tìm GTNN hoặc GTLN:
a/ \(A=\sqrt{9x-x}+\sqrt{29}\)
b/ \(B=\left(x^4+4\right)^4\)
c/ \(C=\sqrt{421}-\sqrt{124-x}\)
d/ \(D=1-\sqrt{5}\left(\sqrt{x}-\sqrt{3}\right)^2\)
MinA = 29 \(\Leftrightarrow x=0\)
Min B= 625 \(\Leftrightarrow x=\left[{}\begin{matrix}x=-1\\x=1\end{matrix}\right.\)

751+65=816 nhé
tk mình đi mình đang cày ních
Giá trị của biểu thức: 751 x 68 + 751 x 32 là:
751.68+751.32
=751.(68+32)
=751.100
=75100
751 x 68 + 751 x 32 = 751 x (68 + 32)
= 751 x 100
= 75100
