Since we know that 2222=16 and 217=34, we can write it out as 2222217. Since 22=4, we can rewrite it as 44217=16217=3217. To get this, we can separate 17 into (10+7) and using the distributive property we get 32(10+7)=3210+327=320+224=544.
The four problems can be written as 16217, then 3217, then 32(10+7), then 320+224
