The numbers multiplied by itself that will give 4, 36, 64, 121 are 2, 6, 8 and 11 respectively

These are perfect squares number, such as

4, 9, 16, 25, 36 etc

4 = 2 × 2 = 2²

36 = 6 × 6 = 6²

64 = 8 × 8 = 8²

121 = 11 × 11 = 11²

other examples of perfect squares are

1 × 1 = 1 = 1²

3 × 3 = 9 = 3²
