Who is asking: Student Question: If you raise 7 to the 500th power, what is the numeral that will appear in the units digit position? |

Hi, The first step is to experiment a little. Calculate 572 and
573 = 572 Now I suggest that you look at The units digit of 3 to the 58th power and The units digit of 2 to the power of 31921 to see how these problems are solved. Cheers, |
