Question

3 mu 3 nhan 9 tru 3 mu 4 nhan 3 cong 5 mu 8 nhan 5 mu 0 tru 5 mu 12  chia 25 mu 2

Answer 1

= 3^6 - 4 x 3 + 5^8 x 5^0 : 25^2

= 729 - 12 + 5^8 x 5^0 : 5^4

= 729 - 12 + 5^4

= 729 - 12 + 625

= 717 + 625

= 1342

Answer 2

bằng 0

Answer 3

\(3^3.9-3^4+5^8.5^0-5^{12}:25^2\)

\(=27.9-81+3905625.1-244140625:625\)

\(=-1235961951^{13}\)

Answer 4

3³.9-3⁴.3+5⁸.5⁰ - 5¹²: 25²

= 3³.9 -3³.3.3+5⁸.1- 5¹²: (5²)²

= 3³.9 -3³.9 +5⁸ - 5¹²: 5⁴

= 0 +5⁸-5⁸

= 0+0

=0

nha

Answer 5

= 27 nhân 9 - 81 nhân 3+390625

=243-243+390625

=0+390625

=390625
