Subtracting indices with same base

WebThe rule for dividing same bases is x^a/x^b=x^ (a-b), so with dividing same bases you subtract the exponents. In the case of the 12s, you subtract -7- (-5), so two negatives in a row create a positive answer which is where the +5 comes from. In the x case, the exponent is positive, so applying the rule gives x^ (-20-5). WebSubtracting exponents with different base Exponents with different bases are computed separated and the results subtracted. On the other hand, variable with unlike bases can …
