pls mathematicians in the house can you solve this log question log3^2-log3 |

ashraf267:log3 1 Like |

The answer is 2 |

Answer should be log3. Log3^2 - log3 = 2(log3) - log3 It's just like saying 2x - x which equals x. Same way, 2log3 - log3 = log3 If the base is 3, Log3 to base 3 equals 1. 1 Like |

The answer is log3. |

Log3^2 - log3 2log3 - log3 2log3/log3 =2 |

onihaxxy: Nah its like saying...x^2 - x.....but because of its base and an inclusion of a logarithm function, the laws of logarithm should simply be applied... Making the equation 2x/x..... = 2.... Put x= log3... |

ashraf267:2log3 - log3 = log3(2-1) = log3(1) = log3 |
Re: mathematicians solve this questions am confused about the answer pls help by femi4: 4:46pm On Jan 01, 2018 |
dtribunal:Wrong, answer is log3 cos that base is 10. Log3 is the same as log103 1 Like |

ashraf267:= 2log3 - log3 = log3 Just like 2x - x = x |
Re: mathematicians solve this questions am confused about the answer pls help by Red2C(m): 7:40pm On Jan 01, 2018 |
dtribunal:D law is log(m ÷ n) = logm - long ...Not: logm/logn = logm - logn 2 Likes |

Jeeeez.... I hate maths |

Chai! This op na olodo! This small question wey pry 2 student fit answer within 2min. Well, they said it's log 3 ![]() |
Re: mathematicians solve this questions am confused about the answer pls help by Matinoh: 4:16pm On Jan 03, 2018 |
onihaxxy: can it also be. log3^2 - log 3 = log(3^2/3). = log (9/3). = log 3 1 Like |
