(1) The base is 11 and the index is 4; this means that 11 is repeated four times. So, the multiplication form is 11 × 11 × 11 × 11.
(2) The base is 6 and the index is 2; this means that 6 is repeated two times. So, the multiplication form is 6 × 6.
(3) The base is 10 and the index is 4; this means that 10 is repeated four times. So, the multiplication form is 10 × 10 × 10 × 10.
(4) The base is 5 and the index is 3; this means that 5 is repeated three times. So, the multiplication form is 5 × 5 × 5.
(5) The base is 8 and the index is 5; this means that 8 is repeated five times. So, the multiplication form is 8 × 8 × 8 × 8 × 8.
