Đây là bài nghe nha bạn, bạn cung cấp audio để bọn mình giúp nha

mình ko chắc là đúm đau

bé,má,bao la,học hành,xấu xí you no biết

bé, mệ, bao la, nghiên cứu, không đẹp.

a: \(2\cdot3\cdot6\cdot6\cdot6=6\cdot6\cdot6\cdot6=6^4\)

b: \(4\cdot4\cdot5\cdot5\cdot5=4^2\cdot5^3\)

\(a,2.3.6.6.6\)

\(=6.6.6.6\)

\(=6^4\)

\(b,4.4.5.5.5\)

\(=4^2.5^3\)

được

\(\dfrac{1}{2}\)\(x^2\) = \(\dfrac{1}{4}x^2\) + \(\dfrac{1}{4}\)\(x^2\)

I used to lose in my work

đk vậy bạn,bỏ từ interest à?

\(64=8^2;100=10^2\)

\(121=11^2\)

\(169=13^2\)

\(196=14^2\)

\(289=17^2\)

64=8²

100=10²

121= 11²

169=14²

289=17²

6,2x+3,1x=4,65

=>9,3x=4,65

=>x=4,65:9,3=0,5

6,2x+3,1x=4,65

x.(6,2+3,1)=4,65

9,3.x=4,65

x=4,65:93

x=0,5

\(\left(2x-1\right)\left(3x+1\right)+\left(3x+4\right)\left(3x-2\right)=5\)

=>\(6x^2+2x-3x-1+9x^2-6x+12x-8=5\)

=>\(15x^2+5x-9-5=0\)

=>\(15x^2+5x-14=0\)

\(\Delta=5^2-4\cdot15\cdot\left(-14\right)=25+60\cdot14=25+840=865>0\)

Do đó: Phương trình có hai nghiệm phân biệt là:

\(\left[{}\begin{matrix}x=\dfrac{-5-\sqrt{865}}{2\cdot15}=\dfrac{-5-\sqrt{865}}{30}\\x=\dfrac{-5+\sqrt{865}}{30}\end{matrix}\right.\)
