5.4^15.9^9-4.3^20.8^9/5.2^9.6^19-7.2^29.27^6
C = 5.4^15.9^9-4.3^20.8^9 / 5.2^9.6^19-7.2^29.27^6
Tính nhanh:
5.4^15.9^9-4.3^20.8^9
5.2^9.6^19-7.2^29.27^6
Giúp mình giải bài này nhé : (5.4^15.9^9-4.3^20.8^9) : (5.2^9.6^19-7.2^29.27^6)
a, (7.6^10.2^20.3^6-2^19.6^15) : (9.6^19.2^9-4.3^17.2^20)
b, (5.4^15.9^9-4.3^20.8^9) : (5.2^9.6^19-7.2^29.27^6)
A=5.4^15.9^9-4.3^20.8^9 và B=5.2^9.6^19-7.2^29.27^6.
Tim A,B
cho A=5.4 mũ 15.9 mũ 9-4.3 mũ 20.8 mũ 9
B=5.2 mũ 9.6 mũ 19-7.2 mũ 29.27 mũ 6
1) tính
5.4^15.9^9-4x3^20.8^9/5.2^9.6^19-7.2^29.27^6
Tính:
B=5.4^15.9^9-4.8^20.8^9/5.2^9.6^19-7.2^29.27^6
