Question

Thực hiện phép tính:

\(A=\frac{2^{12}.3^5-4^6.9^2}{\left(2^2.3\right)^6+8^4.3^5}\) \(-\frac{5^{10}.7^3-25^5.49^2}{\left(125.7\right)^3+5^9.14^3}\)

Answer 1

nhấn máy tính đi bn cho nhanh đỡ phải hỏi

Answer 2

A=\(\dfrac{2^{12}.3^5-2^{12}.3^4}{2^{12}.3^6+2^{12}.3^5}-\dfrac{5^{10}.7^3-5^{25}.7^4}{5^9.7^3+5^9.2^3.7^3}\)

A=\(\dfrac{2^{12}.3^4\left(3-1\right)}{2^{12}.3^5\left(3-1\right)}-\dfrac{5^{10}.7^3\left(1-5^{15}.7\right)}{5^9.7^3\left(1+2^3\right)}\)

A=\(\dfrac{1}{3}-\dfrac{5-5^{16}.35}{9}\)

Vậy A=\(\dfrac{1}{3}-\dfrac{5-5^{16}.35}{9}\)
