Question

tính : 2 mũ 3 x 3 mũ 4 + 92 x 81 - 6 mũ 3 x 5

 

Answer 1

2³.3⁴ + 92.81 - 6³.5

= 8.81 + 92.81 - 216.5

= 81.(8 + 92) - 1080

= 81.100 - 1080

= 8100 - 1080

= 7020

Answer 2

2³ . 3⁴+92.81-6³.5

=8.81+92.81-216.5

= 81.(8+92)-1080

=81.100-1080

=8100-1080

= 7020

Answer 3

2³ x 3⁴ + 92 x 81 - 6³ x 5

=8 x 81 + 92 x 81 - 216 x 5

=648 + 7452 - 1080

=7020
