Giải đáp+Lời giải và giải thích chi tiết:
{150-[50.5^2+25.2-5^2 . 5^3]} : 5:5
=[150-(50.25+50-5^5)] : 5:5
=[150-(1250+50-3125)]:5:5
= [150-(1300-3125)]:5:5
=[(150-(-1825)] :5:5
=(150+1825) :5:5
=1975 : 5:5
=395:5
=79
Giải đáp:
C1: {150-[50.5²+25.2-5².5³]:5:5}
= {150-[1250+50-3125]:5:5}
= {150-(-1825):5:5}
= 150-(-729)
= 879
C2: {150-[50.5²+25.2-5².5³]}:5:5
= {150-[1250+50-3125]}:5:5
= (150+1825):5:5
= 1975:5:5
= 79
