= [(75 + 175).\(5^4\)] : (20.5.5.125 - 625.75)
= (250.625): ( 100. 625 - 625.75)
= (250.625): [(100 - 75).625]
= 250.625 : 25.625
= (250:25).625
= 10.625
= 6250
\(\frac{75.5^4+175.5^4}{20.25.125-625.75}=\frac{5^2.3.5^4+5^2.5^4.7}{4.5^2.5^3.5-5^4.5^2.3}=\frac{5^6\left(3+7\right)}{5^6\left(4-3\right)}=\frac{10}{1}=10\)
Đoạn cuối mình làm hời nhầm tí
= 250.625: 25.625
= (250:25).(625:625)
= 10. 1= 10
