tính giá trị biểu thức 

Answer 1

=(45.5)^10/75^10

=(225/75)^10

=3^10

=59049

Answer 2

\(\frac{45^{10}\cdot5^{10}}{75^{10}}=\frac{3^{10}\cdot15^{10}\cdot5^{10}}{75^{10}}=\frac{3^{10}\cdot3^{10}\cdot5^{10}\cdot5^{10}}{3^{10}\cdot25^{10}}=\frac{3^{10}\cdot3^{10}\cdot5^{10}\cdot5^{10}}{3^{10}\cdot5^{10}\cdot5^{10}}=\frac{3^{20}\cdot5^{20}}{3^{10}\cdot5^{20}}=3^{10}\)

Answer 3

=(45.5)^10/75^10

=225^10/75^10

=(225/75)^10

=3^10

=59049

Answer 4

\(\frac{45^{10}\times5^{10}}{75^{10}}\)

\(=\frac{\left(45\times5\right)^{10}}{75^{10}}\)

\(=\frac{225^{10}}{75^{10}}\)

\(=\left(\frac{225}{75}\right)^{10}\)

\(=3^{10}\)
