21978 x 4 = 87912 (Eighty seven thousand nine hundred twelve)
21978
A five-digit number multiplied by four that results in its inverse (where the digits are reversed) is 21978. When you multiply 21978 by 4, you get 87912, which is the reverse of 21978. This interesting property showcases a unique relationship between certain numbers and their inverses under multiplication.
21978
Let the five-digit number be represented as ( x ). We need to find ( x ) such that ( 4x ) equals the reverse of ( x ). We can express ( x ) as ( 10^4a + 10^3b + 10^2c + 10d + e ) (where ( a, b, c, d, e ) are the digits of ( x )), then ( 4x ) becomes ( 4(10^4a + 10^3b + 10^2c + 10d + e) ). After exploring possible five-digit values, the number ( 21978 ) satisfies the condition because ( 4 \times 21978 = 87912 ), which is indeed ( 21978 ) with its digits reversed.
