Finding the Last Digit of a Power Brilliant Math & Science Wiki
WebFor instance, the unit digit in the number 37 is 7 (n). Next, divide the power of the number by 4. In case the power is exactly divisible by 4, i.e. the remainder is zero, then the unit digit of x^y will be 6, if n = 2,4,6, and 8. the unit digit of x^y will be 1, if n = 3,7, and 9. In case the power is not exactly divisible by 4, i.e. y = 4k ... WebExample: Finding the Unit digit of following numbers: 189 562589743 = 9 (since power is odd); 279 698745832 = 1 (since power is even); 154 258741369 = 4 (since power is odd); 194 65478932 = 6 (since power is even). Digits 2, 3, 7 & 8: These numbers have a power cycle of 4 different numbers. WebMany mathematical contests ask students to find the last digit (or digits) of a power.
