a) 99 - (74 - 129) : 5 + 2022⁰

= 99 - (-55) : 5 + 1

= 99 - (-11) + 1

= 110 + 1

= 111

Diện tích mảnh vườn:

   10x8=80 (m²)

Diện tích miếng đất để trồng rau:

   7x7=49 (m²)

Diện tích lối đi:

  80-49=31 (m²)

Chi phí làm lối đi là:

   110000x31=3410000 (đồng)

Số 11 là số nguyên tố vì 11 chỉ chia được cho chính nó và 1
