`x^5 *5x+3x^2 *x^4`
`=5*(x^5*x)+3*(x^2*x^4)`
`= 5x^6 +3x^6`
`=8x^6`
`x^5 *5x+3x^2 *x^4`
`=5*(x^5*x)+3*(x^2*x^4)`
`= 5x^6 +3x^6`
`=8x^6`
Tìm số tự nhiên x biết:
(x+2)-2=0
(x+3)+1=7
(3x-4)+4=12
(5x+4)-1=13
(4x-8)-3=5
8-(2x-4)=2
7+(5x+2)=14
5-(3x-11)=1
Giúp e vs ạ(Vui lòng trình bày ạ)
Tìm STN x, biết
1) (x + 2) - 2 = 0 2) (x + 3) + 1 = 7
3) (3x - 4) + 4 = 12 4) (5x + 4) - 1 = 13
5) (4x - 8) - 3 = 5 6) 3 + (x - 5) = 7
7) 8 - (2x - 4) = 2 8) 7 + (5x + 2) = 14
9) 5 - (3x - 11) = 1 10) 16 - (8x + 2) = 6
5x^2 (3x -1/5 x^2 +2x^4 -x^5)
giúp mình giải bài toán.......
1)3x-6=5x+2
2)15-x=4x-5
3)x-15=6+4x
4)-12+x=5x-20
5)7x-4=20+3x
6)5x-7=-21-2x
7)x+15=20-4x
8)17-x=7-6x
9)-4|x-2|=-8
10)-7|x+4|=2.(-7)
a) 16+|2x+5|-|x-1|=5x+9
b) 105+|3x-7|+|5x-2=405
c) 302-|x+4|-|3x-7|=9
d) 415+|4-x|+|8x-2|=515
1/ 3(x - 1) - 5(x - 2) = 4(x + 1)
2/ -2(x - 2) - 4(x + 1) = -3(x + 3)
3/ 3x\(^2\) + 2x = 0
4/ x\(^2\) - 5x = 0
5/ (2x - 3)\(^2\) = 36
6/ (5x - 1)\(^3\) = 125
7/ 3\(^x\) + 1 = 27
Tìm x biết a 3 2x 95b 9 . 5 x 3 6.56 3 . 56c 5x 4 3 . 5x 3 511 . 2d 3x 2 4 . 3x 1 1 . 36e 5x 3 105.6344.33 Giups mk vs nhé các cậu .
Tìm x biết :
a, 1/3 - 2/5 + 3x = 3/4
b, 2 x ( 3/4 - 5x ) = 4/5 - 3x
Tìm x, biết:
1) 14x - 5 = 8x + 10
2) 15 + 5x = 3x + 30
3) 2x - 5 = 15- 3x
4) 2 ( 3x + 5 ) + 3 ( x + 1 ) = 6x + 20
5) 4 ( x - 3 0 + 5 ( x - 3 ) = 18
