ai giúp mình câu này với,mình tick cho
a)\(\left(-\frac{1}{2}\right)^2:\left(1\frac{5}{16}-\sqrt{4}+\frac{1}{2}\right)+2008^0\) b)\(7\frac{1}{6}:\left(-\sqrt{\frac{49}{36}}\right)+10\frac{5}{6}.\left(-\frac{14}{2^2.3}\right)+\left|-\frac{1}{2}\right|\)
c)\(\left(-\frac{1}{2}\right)^2+5\frac{1}{2}\left(4,5-\sqrt{\sqrt{16}}\right)+\frac{2^3}{-\left|-2\right|^2}\) d)\(\frac{4^2.8^6.9^{13}}{6^6.16^2.27}\)
a)
1/4:(31/16-2+1/2)+1
=1/4:(-1/16+1/2)+1
=(1/4:7/16)+1
=4/7+1
=11/7
b)
43/6:(-7/6)+65/6.(-7/6)+1/2
=-43/7+-455/36+1/2
=-4607/252
c)
1/4+11/2.5/2+-2
=23/4.5/2+-2
=115/8+-2
=99/8
d) bài 4 rất dễ bạn tự làm đi nhé
tick cho mk đi nhanh lên đó nhiên
=
1/4:(31/16-2+1/2)+1
=1/4:(-1/16+1/2)+1
=(1/4:7/16)+1
=4/7+1
=11/7
b)
43/6:(-7/6)+65/6.(-7/6)+1/2
=-43/7+-455/36+1/2
=-4607/252
c)
1/4+11/2.5/2+-2
=23/4.5/2+-2
=115/8+-2
=99/8
1/4:(31/16-2+1/2)+1
=1/4:(-1/16+1/2)+1
=(1/4:7/16)+1
=4/7+1
=11/7
b)
43/6:(-7/6)+65/6.(-7/6)+1/2
=-43/7+-455/36+1/2
=-4607/252
c)
1/4+11/2.5/2+-2
=23/4.5/2+-2
=115/8+-2
=99/8
