Question

(10^3+10^4+125^2) :5^3

- Tính nhanh nha

Answer 1

\(=10^3:5^3+10^4:5^3+125^2:5^3\)

\(=2^3+2^3\times10+125\)

\(=8+80+125\)

\(=88+125\)

\(=213\)

Answer 2

( 10 mũ 3 + 10 mũ 4 + 125 mũ 2 ) : 5 mũ 3

= (1000 + 10000 + 5 mũ 3 .2 ) : 5 mũ 3

= ( 1000 + 10000 + 5 mũ 6 ) ;  5 Mũ 3

= ( 11000 + 15625 ) : 125

= 26625 : 125

=  213
