In order they are
1.1 * 10^12, 9.5 * 10^11 and 5*10^8
Answer:
114,250
Step-by-step explanation:
Enid invested 43,750
Eddie invested 92,000
the difference is 114,250
1 1/2 pounds
16 ounces = 1 pound
8 1/4 pounds = 132 ounces
132 ounces/ 6 cakes = 22
22 ounces = 1 1/2 pounds
i ^1 = i
i ^ 2 = - 1
i ^ 3 = - i
i ^4 = 1
etc.
................
"i" raised to an odd power cannot simplify to be : A ) - 1
