\(a.6^2:4.3+2.5^2=36:4.3+2.25=9.3+50=27+50=77\)

\(b.2.\left(5.4^2-18\right)=2.\left(5.16-18\right)=2.\left(80-18\right)=2.62=124\)

Soory i was wrong.I forgot to write "fruit" into plural form so remember to write"fruits" into your homework!

Good luck!

He ate all the fruit despite the fact that they were green.

About 2 weeks ago,Thuy and I enjoyed Huy's birthday party.It started at 8:00 pm.We had a great time together with Huy and his friends.We met new friends,sang,ate birthday cake and lots of sweets and fruits,play a lots of awesome games(sorry i just can listing,if you don like it,you can change this to another sentence and don't write the sentence which is on this parentheses to your paragraph).When the party ended,he thanked us about coming to his party.It was the best day ever!
