Tk mk nha

a) 535,5 : 0,01 = 53550

b)  23,6 x 1000 = 23600

c) 168,86 x 0,1 = 16,886

d) 7,45 : 100 = 0,0745

a = 53550

b = 23600

c = 16,886

d = 0,0745

a) 7,89

b) 2398 

c) 58,85 

d) 14 

\(\text{a. 78,9 : 2,5 : 4. }\)

\(=31,56:4=7,89.\)

\(\text{ b. 56,75 + 8,4 : 4}.\)

\(=56,75+2,1=58,85.\)

\(\text{c. 23,6 x 100 + 2,9 : 0,1. }\)

\(=2360+29=2389.\)

X - 123,6 = 7,2 : 0,12

X - 123,6 = 60

            x = 60 + 123,6

            x = 183,6

=183,6 nha bạn

\(A=\left|x-101\right|-101\)

\(\left|x-101\right|\ge0\)

\(\Rightarrow\left|x-101\right|-101\ge-101\)

\(\Rightarrow A\ge101\)

\(\Rightarrow MIN_A=101\Leftrightarrow\left|x-101\right|=0\)

\(\Rightarrow x=101\)

vay_

Vì x = 100 => x + 1 = 101

=> f(100) = x⁸ - (x + 1)x⁷ + (x + 1)x⁶ - .... + (x  +1)x² - (x  +1)x + 25

= x⁸ - x ⁸ - x ⁷ + x⁷ + x⁶  -.... + x³ + x² - x² - x + 25 

= -x + 25 = -100 + 25 = -75
