Question

Tính giá trị của các biểu thức :

8² x 4³ phần 16³

25² x 125 phần 5³ x 5⁴

Answer 1

\(\frac{8^2.4^3}{16^3}=\frac{\left(2^3\right)^2.\left(2^2\right)^3}{\left(2^4\right)^3}=\frac{2^6.2^6}{2^{12}}=1\)

\(\frac{25^2.125}{5^3.5^4}=\frac{\left(5^2\right)^2.5^3}{5^4.5^3}=\frac{5^4.5^3}{5^4.5^3}=1\)

Answer 2

\(\frac{8^2.4^3}{16^3}=\frac{\left(2^3\right)^2.\left(2^2\right)^3}{\left(2^4\right)^3}=\frac{2^6.2^6}{2^{12}}=1\)

\(\frac{25^2.125}{5^3.5^4}=\frac{\left(5^2\right)^2.5^3}{5^3.5^4}=\frac{5^4.5^3}{5^3.5^4}=1\)

Answer 3

\(\frac{8^2.4^3}{16^3}=\frac{\left(2^3\right)^2.\left(2^2\right)^3}{\left(2^4\right)^3}=\frac{2^6.2^6}{2^{12}}=1\)

\(\frac{25^2.125}{5^3.5^4}=\frac{\left(5^2\right)^2.5^3}{5^3.5^4}=\frac{5^4.5^3}{5^3.5^4}=1\)
