5^{7} = 7^{5} | |

The surface area of a cone is equal to (1/3)π(radius)^{2}x(height). | |

1^{3}+2^{3}+ ... +n^{3} = (1+2+ ... + n)^{2} | |

To square a two-digit number with N in the tens place and 5 in the ones place, the answer is always (N^{2}+N) as the first two digits and 25 as the last two. | |

'e' is a rational number. | |

1 is a prime number. | |

On a radian-based graph, sin(0)=sin(π). | |

For a three-digit number where all three digits are the same, the number divided by the sum of the digits in the number is equal to 27. | |

A parabola is always mirror-symmetrical. | |
