b)a) A = (-1436) - (-1586) + |-532| - (568+468) + 1434
A=-1436+1586+532-1036+1434
A=150+532-1036+1434=1080
b)B=\(\frac{18^6.2^{12}.4^3.9^3}{16^3.6^9.27^3}=\frac{2^6.3^{12}.2^{12}.2^6.3^6}{2^9.2^9.3^9.3^9}=\frac{2^{24}.3^{18}}{2^{18}.3^{18}}=2^6\)

Bài 1. (4 điểm) Tính:
1)
A= (-1436) - (-1586+ -532 ) - (568+ 468) +1434 .
Tính :
A = -1436 - -1586 + |-532| - (568+468) + 1434
A=-1436-(-1586+532)-(568+468)+1434
A=(-1436)-(-1586+|-532|)-(568+468)+1434
cho a=18^4.2^12.4^3.9^3/16^3.6^9.27^3
tìm a.nhanh nhé
Tính:
$\frac{18^2 . 2^{12} . 4^3 . 9^3}{16^3.6^9.27^3}$
tính giá trị biểu thức
a) A= \(\dfrac{16^5.15^5}{2^{10}.3^5.5^4}\)
b) B= \(\dfrac{2^{15}.3+2^{19}.10}{2^{12}.26}\)
c) C= \(\dfrac{9^5.30^3}{3^{15}.5^3.6^2}\)
d) D= \(\dfrac{3^{11}.4+3^{11}.5}{3^3.9^5}\)
giúp mik mik sẽ tik cho nhé
tính gt biểu thức
A= \(\dfrac{9^5.30^3}{3^{15}.5^3.6^2}\)
B= \(\dfrac{3^{11}.4+3^{11}.5}{3^3.9^5}\)
giúp mik đang cần gấp
Tính
\(A=\frac{4}{1.3}+\frac{12}{3.9}+\frac{16}{9.17}+\frac{30}{17.32}+\frac{26}{32.45}+\frac{10}{45.50}+\frac{34}{50.67}\)
