Question

Use prime factorization method to find the square root of each of the following :
c) 1089

The correct answer is: 33


    c) Let's find the prime factorization of the number.
    1089
    = 3 × 363
    = 3 × 3 × 121
    = 3 × 3 × 11 ×1 1
    equals 3 squared cross times 11 squared equals left parenthesis 3 cross times 11 right parenthesis squared equals 33 squared
    The square root of 1089 is 33.
