2.22%2A10%5E%28-12%29+%2F+4.1%2A10%5E%28-33%29
Multiply top and bottom by 10%5E33
%282.22%2A10%5E%28-12%29+%2F+4.1%2A10%5E%28-33%29%29+%2A+%2810%5E33%2F10%5E33%29
2.22%2A10%5E%28-12%29%2A10%5E33+%2F+%284.1%2A10%5E-33%2A10%5E33%29
because the general rule is 10%5E%28-a%29%2A10%5Ea+=+10%5E0
and 10%5E0+=+1
2.22%2A10%5E%28-12%29%2A10%5E33+%2F+4.1%2A1
Another rule is 10%5E%28-a%29%2A10%5Eb+=+10%5E%28b-a%29, so
2.22%2A10%5E21%2F4.1
Change the numerator to an equivilant number
22.2%2A10%5E20
22.2%2A10%5E20+%2F+4.1+=+5.41%2A10%5E20 answer
