Que. | Given a boolean function f (x1, x2, ..., xn), which of the following equations is NOT true |

a. | f (x1, x2, ..., xn) = x1'f(x1, x2, ..., xn) + x1f(x1, x2, ..., xn) |

b. | f (x1, x2, ..., xn) = x2f(x1, x2, …, xn) + x2'f(x1, x2, …,xn) |

c. | f (x1, x2, ..., xn) = xn'f(x1, x2, …, 0) + xnf(x1, x2, …,1) |

d. | f (x1, x2, ..., xn) = f(0, x2, …, xn) + f(1, x2, .., xn) |

Answer:f (x1, x2, ..., xn) = f(0, x2, …, xn) + f(1, x2, .., xn) |
