2 | 3/4/2017 6:21:46 | Both are equal | 3^5=(3x3x3x3x3) so actually 3^5 can be written as (3^4x3). 3^4+3^4+3^4 can actually be also written as (3^4x3) because it is 3 groups of 3^4. Thus, since both 3^4+3^4+3^4 and 3^5 are equal to (3^4x3), both are equal. | Christabel Lee | 1 | 1 | 5 | 3 | 8 | |

3 | 3/4/2017 8:32:50 | Both are equal | 3^4 + 3^4 + 3^4 = 3^4 x 3^1. When multiplying numbers that are the same but have different powers, we just add the two powers together. For example, 2^3 x 2^1 = 2^4. So, 3^4 x 3^1 = 3^5. Hence, they are both equal. | Ethan Loke | 13 | 1 | 3 | 3 | 6 | |

4 | 3/4/2017 11:49:13 | 3^4 + 3^4 + 3^4 (Note: 3^4: THREE to the power of FOUR) | 3=a 3^4+3^4+3^4=3a^4 3^5=a^5=a^5 | Lucas(Correct answer-Ignore the second one) | 15 | 1 | 1 | 0 | 1 | You could have simplified without substituting a = 3. The pattern could be more obvious if you only use "3" |

5 | 3/4/2017 8:47:56 | Both are equal | 3^5= 3^4 x 3 which is equal to 3^4+3^4+3^4 | Sara Woo | 6 | 2 | 3 | 3 | 6 | |

6 | 3/4/2017 12:36:21 | Both are equal | First, times the powers of the three and times three like 4x4x4=64 64x3=243 which is 3^5 | Ho Rui Yang | 10 | 2 | 1 | 1 | 2 | Explanation not clear. Why introduce 4x4x4=64? |

7 | 3/4/2017 6:51:24 | 3^4 + 3^4 + 3^4 (Note: 3^4: THREE to the power of FOUR) | I added the 3^4 together and tried to estimate the answer. | Zuhairi | 17 | 2 | 5 | 0 | 5 | Do not estimate. There's a way to work out the answers without calculator. (Clue: Algebra) |

8 | 3/4/2017 21:45:03 | 3^5 (i.e. THREE to the power of FIVE) | 3^4 + 3^4 + 3^4 = 3^12. This is definitely larger than 3^5. | Muhammad Adam Aqasha | 18 | 2 | 1 | 0 | 1 | Check your interpretation of the "Power" |

9 | 3/4/2017 6:11:58 | Both are equal | 3^4+3^4+3^4+3^4 is basically equals to 3*3*3*3+3*3*3*3+3*3*3*3+3*3*3*3 so comparing that to 3^5 which is 3*3*3*3*3, if you look carefully, you can actually see that to calculate 3^4+3^4+3^4 it is basically 3^4*3. Thus, also to calculate 3^5, it would be 3*3*3*3*3, thus it is actually the same as 3^4*3. So 3*3*3*3*3 if you take apart 4 threes, and out it together,you would get 3^4*3. So is you compare this to the answer just now, it as exactly the same. Thus my answer is both are equal. | Qin Guan | 21 | 2 | 5 | 3 | 8 | |

12 | 3/4/2017 6:59:26 | 3^4 + 3^4 + 3^4 (Note: 3^4: THREE to the power of FOUR) | 3^4 is equal to 3x3x3x3. So 3^4+3^4+3^4 is equal to(3x3x3x3)+(3x3x3x3)+(3x3x3x3) while 3^5 is just 3x3x3x3x3 which is way lesser than 3^4+3^4+3^4 thus i arrive at my answer. | Hao Min | 7 | 4 | 5 | 0 | 5 | Relook at your explanation. You attempted to demonstrate your understanding on what 3^4 mean; however, have not made the link ot the 2 arithmetic expressions. |

13 | 3/4/2017 12:56:34 | Both are equal | I know that 3^4 x3 = 9^4=3^5 , so both are the same. | Chong Yao Kiat corwin | 8 | 4 | 1 | 1 | 2 | Explanation not clear. Why introduce "9"? |

14 | 3/4/2017 6:45:20 | Both are equal | 3^5 is equal to 3^4 x 3. Therefore, both are equal. | Jia zeyu | 11 | 4 | 5 | 3 | 8 | |

15 | 3/4/2017 9:48:22 | 3^4 + 3^4 + 3^4 (Note: 3^4: THREE to the power of FOUR) | I first found out the total of both options then compared from there. | Joel Chew | 12 | 4 | 1 | 0 | 1 | Check your calculation. You can actually apply what you know in algebra ot solve this problem without working out the values. |

16 | 3/6/2017 20:00:07 | Both are equal | 3^4*3=3^5 so equal | Xee Zun Kye | 25 | 4 | N.A. | Correct | N.A. | |

17 | 3/7/2017 14:37:03 | Both are equal | Using a calculator. | Richard Kok Zen Xian | 22 | 2 | ||||
