Tìm x
A. (x+3)3=1000
B. (x+1)2=25
C. (x-7)4=16
D. ( x - 3 ) 4 = 81
tính nhanh
A = 1 x 2 x3 + 2 x 3 x 4 + ..... + 99 x 100 x 101
B = 1 x 2 + 2 x 3 + 3 x 4 +.......+ 999 x 1000
C = 1 + 4 + 9 + 16 + 25 + 36 + ....+ 10000
D = 1 + 2^2 + 3^2+ 4^2+ 5^2 + ... + 99^2
tìm x
102*105x-2/10x=1000
54x-4/5x*25=1252*5x
1000:[ 30+(2xx-6x-6)]=25
2. tìm x , biết:
a) 2x + 25 = 145
b) 216 : x +34 : x = 10
c) 2017 : x - 17 : x = 1000
d) 4057 + ( 2x : 38 ) =20395
e) ( x + 1 ) + ( x + 4 ) + ( x + 7 ) + ........ + ( x + 28 ) =155
Tìm x thuộc N biết x :17 du 8 x:25 du 10 va 500<x<1000
Điền vào ô trống:
x | 5 | –18 | –25 | |
y | –7 | 10 | –10 | |
x . y | –180 | –1000 |
Tìm x :
a ) ( 9 - 8x ) 2 = 100
b ) ( 20 - x ) 2 = 60
c ) \(\frac{1}{2}x+\frac{8}{4}=\frac{100}{25}\)
d ) ( 90 - x ) 10 = 1000
ai lm dc cho 1000 like
a , x - 5 /7 =9
b)8/25 nhân 46/24 -x=1/4
c)1/5 chia x = 1/3 +3/4
d , 2 / 5 . x +1/7 .x = 2/3
e)( 3 cách 1/2 - 2x ) 1 cách 1/3 =7 cách 1/3
