Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.
None of the above. 11^8/11^3 is 11^5 since you will just subtract exponents. The numerical value is 161051 although you should have an option that either is 11^5 or equals 11^5 like 11^15/11^10 for example
