How do you simplify 3 x 3 x 5 x 5 x 5 x 5 x 7?
Count the number of times each digit appears in the multiplication and then write each digit once in the multiplication with the number of times they originally appeared as an index (little superscript number): 3 appears 2 times 5 appears 4 times 7 appears 1 times → 3 x 3 x 5 x 5 x 5 x 5 x 7 = 32 x 54 x 71 However, when the index is 1, it is not normally written, so this becomes: 3 x 3 x 5 x 5 x 5 x 5 x 7 = 32 x 54 x 7
