\(\frac{\left(0,9\right)^5}{\left(0,3\right)^6}=810\)

\(\left(0,125\right)^3.512=1\)

Các cậu nha.

=(250-50)- (0,95x40)x(10x0,1)x(0,125x80)

8. (-1,6) x (-0,125) x (-0,5)

= 8 . [(-1,6) x (-0,125) x (-0,5)]
= 8 . (-0,1)

= -0,8

a) \(17+188+183=205+183=388\)

b) \(80-\left[130-\left(12-4\right)^2\right]\)

\(=80-\left(130-64\right)\)

\(80-66=14\)

c) \(2^3.17-2^3.14\)

\(8.17-8.14\)

\(=8.\left(17-14\right)\)

\(=8.3=24\)

\(80-\left(4.5^2.3.2^2\right)\)

\(=80-\left(4.5.5.3.2.2\right)\)

\(=80-\left(\left[5.2\right].\left[5.2\right].\left[4.3\right]\right)\)

\(=80-\left(10.10.12\right)\)

\(=80-\left(10.120\right)\)

\(=80-1200\)

\(=-1120\)

80-[4.5^2 .3.2^2 ]

=80-[4.25.3.4]

=80-[100.12]

=80-1200=-1120

80 - [ 4 . 5² . 3 . 2² ]

=80 - [ 4 . 5 . 3 . 2 ]

= 80 - 120

= - 40 

0,04 x 0,1 x 25 = (0,04 x 25) x 0,1 = 1 x 0,1 = 0,1

4,86 x 0,25 x 40 = 4,86 x (0,25 x 40) = 4,86 x 10 = 48,6

0,125 x 6,94 x 80 = (0,125 x 80) x (6,94) = 10 x 6,94 = 69,4  

g: =1000+600+130=1730

=(623+377)+(282+318)

=1000+600

=1600+130

=1730

CHưa học số nguyên nha
