Question

giải chi tiết

Answer 1

53: \(\dfrac{8^8}{4^6}=\dfrac{2^{24}}{2^{12}}=2^{12}\)

56: \(\dfrac{8^4}{2^3}=\dfrac{2^{12}}{2^3}=2^9=512\)

59: \(\dfrac{7^5}{14^3}=\dfrac{7^5}{7^3\cdot2^3}=\dfrac{1}{8}\)

62: \(\dfrac{5^5}{\left(-15\right)^4}=\dfrac{5^5}{5^4\cdot3^4}=\dfrac{5}{81}\)

Answer 2

35: \(\dfrac{16^3}{8^3}=2^3=8\)

38: \(\dfrac{27^5}{9^4}=\dfrac{3^{15}}{3^8}=3^7\)

41: \(\dfrac{27^4}{81^5}=\dfrac{3^{12}}{3^{20}}=\dfrac{1}{3^8}\)

44: \(\dfrac{4^7}{8^3}=\dfrac{2^{14}}{2^9}=2^5=32\)0

47: \(\dfrac{64^4}{16^3}=\dfrac{2^{24}}{2^{12}}=2^{12}\)

50: \(\dfrac{9^4}{81^5}=\dfrac{3^8}{3^{20}}=\dfrac{1}{3^{12}}\)
