(2m^-3n^7)^-3 = * Simplify, but DO NOT write as a fraction. Write your answer using exponents for each factor.

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )

It equals 1373.5 that’s the solution

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
