A=5^10 . 7^3 -49^2 . 25^2 / (125.7)^3 + 5^9 . 14
B=212. 35- 46. 92/ (22.3)6 + 84. 35 - 510.73-255. 492/ (125.7)3+59. 143
Rút gọn :
A = \(\frac{2^{12}.3^5-4^6.9^2}{\left(2^2.3\right)^6+8^4.3^5}-\frac{5^{10}.7^3-25^5.49^2}{\left(125.7\right)^3+5^9.\left(14\right)^3}\)
\(B=\frac{^{2^{13}.3^5-4^6.9^2}}{\left(2^2.3\right)^6+8^4.3^5}-\frac{^{5^{10}.7^3-25^5.49^2}}{\left(125.7\right)^3+5^9.14^3}\)
Tính hợp lý:
\(\dfrac{2^{12}.3^5-4^6.9^2}{\left(2^2.3\right)^6}-\dfrac{5^{10}.7^3-25^5.49^2}{\left(125.7\right)^3+5^9.14^3}\)
Bài 1: Tính:
A= ((2^12 . 3^5 - 4^6 . 9^3 ) / 9( 2^2 . 3 )^6 + (8^4 . 3^5))) - ((5^10 . 7^3 - 25^2 . 49^2) / (( 125 . 7 )^3 + 5^9 . 14^3))
B= (2^9 . 27^3 + 15 . 4^9 . 9^4) / (6^9 . 2^0 + 12^10)
tính\(\frac{2^{12}.3^5-4^6.9^2}{\left(2^2.3\right)^6+8^4.3^5}-\frac{5^{10}.7^3-25^2.49^2}{\left(125.7\right)^3+5^9.14^3}\)
Thực hiện phép tính
A=212.35-46.92/(22.3)6+84.35-516.73-255.492/(125.7)3+59.143
Lưu ý dấy . là dấu nhân
Ai giúp với mai nộp rồi!!!!!!!!!!!!
Rút gọn\(a, 2^12×3^5-4^6×9^2 / 12^6+8^4×35 b, 5^10×7^3-25^5×49^2/(125×7)^3+5^9×14^3\)
