\(8^5.16^2.32^4\)

\(=\left(2^3\right)^5.\left(2^4\right)^2.\left(2^5\right)^4\)

\(=2^{15}.2^8.2^{20}\)

\(=2^{15+8+20}\)

\(=2^{43}\)

Chúc bạn hk tốt nha!!!

cảm ơn bạn nhìu

a)\(\left(\frac{1}{5}\right)^{10}.5^{20}=\left(\frac{1}{5}\right)^{10}.5^{10.2}=\left(\frac{1}{5}\right)^{10}.25^{10}=\left(\frac{1}{5}.5\right)^{10}=1^{10}=1\)

b)\(5^2.3^5.\left(\frac{3}{5}\right)^2=\left(\frac{3}{5}.5\right)^2.3^5=3^2.3^5=3^7\)

c)\(\left(\frac{1}{16}\right)^3:\left(\frac{1}{8}\right)^2=\left(\frac{1}{8}\right)^{2.3}:\left(\frac{1}{8}\right)^2=\left(\frac{1}{8}\right)^{6+2}=\left(\frac{1}{8}\right)^8\)

\(a.\left(\frac{1}{5}\right)^{10}.5^{20}=\left(\frac{1}{5}\right)^{10}.5^{10.2}=\left(\frac{1}{5}\right)^{10}.\left(5^2\right)^{10}=\left(\frac{1}{5}\right)^{10}.25^{10}=\left(\frac{1}{5}.25\right)^{10}=5^{10}.\)

\(b.5^2.3^5.\left(\frac{3}{5}\right)^2=\left[5^2.\left(\frac{3}{5}\right)^2\right].3^5=\left(5.\frac{3}{5}\right)^2.3^5=3^2.3^5=3^7\)\(c.\left(\frac{1}{16}\right)^3:\left(\frac{1}{8}\right)^2=\left[\left(\frac{1}{4}\right)^2\right]^3:\left[\left(\frac{1}{2}\right)^3\right]^2=\left(\frac{1}{4}\right)^6:\left(\frac{1}{2}\right)^6=\left(\frac{1}{4}:\frac{1}{2}\right)^6=\left(\frac{1}{2}\right)^6\)

Hì hì xin lỗi trả lời muộn thông cảm

ko bit

a, 20^2 - 6^ 2=  400 - 36 = 364

b,3^3 . 18 - 3^3 . 12 = 3^3 . ( 18-12) = 27 . 6 = 162

c, 39 . 213 + 87 . 39 = ( 213 + 87) . 39 = 300 . 39 = 110700

d, 80 - [ 130 - ( 12 - 4)^2] = 80 - [130 - (3^2) ] = 80 - 130 - 9 = -59

mà đừng đổi ra số tụ nhiên nhế

\(2^7.\frac{3^4}{3^3}.2^5=2^{7+5}.3^{4-3}=2^{12}.3\)

\(\frac{2^7.3^4}{3^3.2^5}=\frac{2^2.3^1}{1}=\frac{4.3}{1}=\frac{12}{1}=12\)

a, \(8^4.16^5\)

b, \(5^{40}.125^2.25^3\)

c,\(27^4.81^{10}\)

d, \(10^3.100^5.1000^4\)

Bạn ơi mình hỏi là viết các tích của số đó chứ ko phải là ghi ra như vậy

8⁴.16⁵=2¹².2²⁰=2³²

5⁴⁰.125².25³=5⁴⁰.5⁶.5⁶=5⁵²

27⁴.81¹⁰=3¹².3⁴⁰=3⁵²

10³.100⁵.1000⁴=10³.10¹⁰.10¹²=10²⁵

^{Cần chi tiết hơn không?}
