If the problem is 19^3 * 19^4 The multiplication rule for exponents is: If the bases are the same, keep the base and add the powers. 19 ^ (3 + 4) = 19^7 LETTER D should be written as 19^7 instead of 197
If 1 bushel = 48 pounds and 1 pound = 3 apples 48 pounds = x apples cross multiply x apples = 48 X 3 ==> 144 apples 1 bushel = 144 apples (because 48 pounds = 1 bushel) 315 bushel = x apples x apples = 144 X 315 x = 45360 apples
