For each of the following exponent multiplication or division problems listed below, find the correct solution. (Note: Round numbers to the nearest one hundredth.)
25 x 25 = 625 x 25 = 15625
15 x 15 = 225
15625 ÷ 225 = 69.44
Solution: 253 ÷ 152 = 69.44
Answer (c) is correct
3 x 3 = 9 x 3 = 27 x 3 = 81
3 x 3 = 9 x 3 = 27 x 3 = 81 x 3 = 243 x 3 = 729
81 x 729 = 59049 ÷ 6 = 9841.5
Solution: 34 x 36 ÷ 6 = 9841.5
Answer (d) is correct
44 x 44 = 1936
11 x 11 = 121
1936 x 121 = 234256
Solution: 442 x 112 = 234256
Answer (b) is correct
7 x 7 = 49
3 x 3 = 9 x 3 = 27 x 3 = 81 x 3 = 243
49 x 243 = 11907
Solution: 72 x 35 = 11907
Answer (c) is correct
17 x 17 = 289
8 x 8 = 64 x 8 = 512
289 - 512 = -223 ÷ 30 = -7.43

20 x 20 = 400
1000 x 400 = 400000 ÷ 500 = 800
Solution: 103 x 202 ÷ 500 = 800
Answer (a) is correct
16 x 16 = 256
2 x 2 = 4 x 2 = 8 x 2 = 16 x 2 = 32
256 ÷ 32 = 8
Solution: 162 ÷ 25 = 8
Answer (d) is correct
6 x 6 = 36 x 6 = 216 x 6 = 1296
