Thank các bn nhìu!!

Answer 1

B = \(\dfrac{30.4^7.3^{29}-5.4^{15}.2^{12}}{54.6^{14}.9^7-12.8^5.7^5}\)

B=\(\dfrac{5.6.\left(2^2\right)^7.3^{29}-5.\left(2^2\right)^{15}.2^{12}}{9.5.\left(2.3\right)^{14}.\left(3^2\right)^7-\left(3.4\right).\left(2^3\right)^5.7^5}\)

B=\(\dfrac{5.\left(2.3\right).2^{14}.3^{19}-5.2^{30}.2^{12}}{3^2.5.2^{14}.3^{14}-3.4.2^{15}.7^5}\)

B=\(\dfrac{5.2^{15}.3^{20}-5.2^{30}.2^{12}}{5.2^{14}.3^{16}-3.2^{17}.7^5}\)

B=\(\dfrac{5.\left(2^{15}.3^{20}-2^{30}.2^{12}\right)}{2^{14}.\left(5.3^{16}-3.2^3.7^5\right)}\)
