If n is an integer and n^4 is divisible by 5, which of the following could be the remainder when n is divided by 5? Select.
A) 1 B) 2 C) 3 D) 4 E) 5
option 1   Remainder 1 means  5+1=

<output>6</output>
6   n^4= 6^4= 6*6*6*6/5 is not an integer   option 2   Remainder 2 means  5+2= 
<gadget id="calculator"> 5+2</gadget>
<output>7</output>
7   n^4= 7^4=7*7*7*7/5 is not an integer   option 3   Remainder 3 means  5+3= 
<gadget id="calculator"> 5+3</gadget>
<output>8</output>
8   n^4= 8^4=8*8*8*8/5 is not an integer   option 4   Remainder 4 means  5+4= 
<gadget id="calculator"> 5+4</gadget>
<output>9</output>
9   n^4= 9^4=9*9*9*9/5 is not an integer   option 5   Remainder 5 means  5+5= 
<gadget id="calculator"> 5+5</gadget>
<output>10</output>
10   n^4= 10*10*10*10/5 is an integer means n^4 is divisible by 5 if we take n=5   so 5 is correct
<result>E</result>
If n is an integer and n^4 is divisible by 5, which of the following could be the remainder when n is divided by 5?
