\(1,=\left(-1436+1434\right)+\left(1586+532\right)-100\\ =-2-100+2118=2016\\ 2,B=\dfrac{2^6\cdot3^{12}\cdot2^{12}\cdot2^6\cdot3^6}{2^{12}\cdot2^9\cdot3^9\cdot3^9}=2^3=8\)
Tính :
A = -1436 - -1586 + |-532| - (568+468) + 1434
A=-1436-(-1586+532)-(568+468)+1434
A=(-1436)-(-1586+|-532|)-(568+468)+1434
Tính :
a) A = (-1436) - (-1586) + |-532| - (568+468) + 1434
b) B = \(\frac{18^6.2^{12}.4^3.9^3}{16^3.6^9.27^3}\)
Cho P =1/285+1/286+...+1/568
Q = 1-1/2+1/3-1/4+...+1/567+1/568
Tính P/Q
C = \(\dfrac{\dfrac{1}{285}+\dfrac{1}{286}+\dfrac{1}{287}+...+\dfrac{1}{568}}{\dfrac{1}{1}-\dfrac{1}{2}+\dfrac{1}{3}-\dfrac{1}{4}+...+\dfrac{1}{567}-\dfrac{1}{568}}\) . Tính C
Giải chi tiết hộ nha__camon
bài 1: tính bằng cách thuạt lợi nhất
1) 532 - ( 232 - 150 )
thank you nha
Tính hợp lí:
a ) 10 17 − 5 13 + 7 17 − 8 13 ; b ) 30 51 − 20 52 + 14 34 − 56 91 − 2 c ) − 10 3 + 13 10 − 1 6 + 7 10 ; d ) 1 − 20 6 + 39 30 − 4 24 + 35 50
1,Tính nhanh
a, 568 + 568 x 135 - 568 x 36
b, 17 x 49 + 49 x 37 + 54 x 26 + 54 x 25
c, 14 x 35 x 5 + 10 x 25 x 7 + 20 x 70
