\(9\left(\dfrac{-1^3}{3}\right)-3\left(\dfrac{-1}{3}^2\right)+2\left(\dfrac{-1}{3}\right)+1\)\(\dfrac{-1}{3}^3\)
help meeeeeee!!
SOS
\(\left(3-x\right)^3=-\dfrac{27}{64};\left(x-5\right)^3=\dfrac{1}{-27};\left(x-\dfrac{1}{2}\right)^3=\dfrac{27}{8};\left(2x-1\right)^2=\dfrac{1}{4};\left(2-3x\right)^2=\dfrac{9}{4};\left(1-\dfrac{2}{3}\right)^2=\dfrac{4}{9}\)
bỏ ngoặc rồi tính
1|(-2/5)+1/3]-(3/5-1/3)
2(3/2-3/4)-(0,25+1/2)
sos
1/9 - 0,3 * 5/9 +1/3 +5
√0,36 - |-0,75 | : (-1 và 3/4)
1 - (5/9 - 2/3) mủ 2 : 4/27
1. Tính
a) (5/4)^3 . ( 4/5)^7
b) (1/3)4 . (-9/2)^6
c) 4^2 . (0.2)^3
d) (0,5)^4 . (-2)^8
e) (2/3)^3 . (8/27)^3
f) (9/10)^6 . (27/-20)^6
Sos cấp cứu bài này .Mai nộp r bài tìm x nha: x+2/-4 =-9/×+2
√0,36 - |-0,75 | : (-1 và 3/4)
1 - (5/9 - 2/3) mủ 2 : 4/27
1>tìm n thuộc N biết:
27^n . 9^n = 9^27 : 81
2>Tìm x biết:
a)(x- 1/2)^3 = 1/27
b)(x + 1/2)^2 = 4/25
Tính hợp lí:
a.[(3/4+11/13-15/27)/(3/2+22/13-10/9)]+(1/1*2)+(1/2*3)+(1/3*4)
b.(7*12^8*5^4-6^9*20^4)/(6^10*10^5-7*3^9*80^4)
