Tính \(\frac{2^5.15^3}{6^3.10^2}\)
1) \(\frac{2^4.2^6}{\left(2^5\right)^2}-\frac{2^5.15^3}{6^3.10^2}\)
\(=\frac{2^{10}}{2^{10}}-\frac{2^5.3^3.5^3}{2^3.3^3.2^2.5^2}\)
\(=1-5=-4\)
ik nhé. tks bạn!

Rut gon bieu thuc:
m=\(\frac{2^5.15^3}{6^3.10^2}\)
\(m=\frac{2^5.15^3}{6^3.10^2}=\frac{2^5.\left(3.5\right)^3}{\left(2.3\right)^3.\left(5.2\right)^2}=\frac{2^5.3^3.5^3}{2^5.3^3.5^2}=5\)\(5\)
\(m=\frac{2^5.15^3}{6^3.10^2}=\frac{2^5.\left(3.5\right)^3}{\left(2.3\right)^3.\left(2.5\right)^2}=\frac{2^5.3^3.5^3}{2^3.3^3.2^2.5^2}=5\)
TÍNH:
a)\(\frac{2^4.2^6}{\left(2^5\right)^2}-\frac{2^5.15^3}{6^3.10^2}\)
b)\(\frac{1}{2}.\sqrt{100}-\sqrt{\frac{1}{16}}+\left(\frac{1}{3}\right)^0\)
Thực hiện phép tính:
a) \(\left(\frac{1}{3}\right)^{50}.\left(-9\right)^{25}.\frac{2}{3}:4\)
b) \(\frac{2^4.2^6}{\left(2^5\right)^2}-\frac{2^5.15^3}{6^3.10^2}\)
a) (1/3)50 . (-9)25 .2/3:4
= (1/3)50 . [-(3)50] . 2/3 . 1/4
= - (1/3.3)50 . 1/6
= -1 . 1/6 = -1/6
b) (24.26)/(25)2 - (25.153)/(63.102)
= 210/210 - (25.33.53)/(23.33.22.52)
= 1- (25.33.53)/(25.33.52)
= 1- 5
= -4
