What is fundamental theorem of arthmetic ? |
|
Answer» According to fundamental theorem of arithmetic every composite number has unique prime factor Every composite number can be expressed (factorised ) as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur.This theorem also says that the prime factorisation of a natural number is unique, except for the order of its factors.For example 20 can be expressed as\xa0{tex}2 × 2 × 5 {/tex}Using this theorem the LCM and HCF of the given pair of positive integers can be calculated.LCM = Product of the greatest power of each prime factor, involved in the numbers.HCF = Product of the smallest power of each common prime factor in the numbers. |

Answer» 1 1 because we can change sec(90 - theta) = cosec .... Then sin×cosec = sin ×1/sin from sin to sin cancel out the results is 1............... Hlo... Hlo.. Anyone present here?? Queen se original name pe?? Hii Hlo aadya and suhu 1 1? Sin theta × cosec theta => sin theta × 1/sin theta => 1 1 |

Prove that... √sec²Ø + cosec²Ø = tanØ + CotØ |
|
Answer» ?? Sorry...last se 2nd wali ye hogi...√(tan theta +cot theta)2 LHS - √sec2theta + cosec2theta => √(1+tan2theta)+(1+cot2theta) => √(tan2theta + cot2theta + 2) => √(tan2theta + cot2theta + 2×tan theta × 1/tan theta) => √(tan2theta + cot2theta + 2×tan theta × cot theta) => √(tan2theta + cot2theta)2 => tan theta + cot theta Now, LHS = RHS...So, it\'s prove.. |

Prove root p is irritational number |
| Answer» If possible,let √p be a rational number.also a and b is rational.then,√p = a/bon squaring both sides,we get,(√p)²= a²/b²→p = a²/b²→b² = a²/p [p divides a² so,p divides a]Let a= pr for some integer r→b² = (pr)²/p→b² = p²r²/p→b² = pr²→r² = b²/p [p divides b² so, p divides b]Thus p is a common factor of a and b.But this is a contradiction, since a and b have no common factor.This contradiction arises by assuming √p a rational number.Hence,√p is irrational. | |

Prove that 5-root 3is irritational number |
| Answer» Let us assume that 5 - √3 is rational. Then it can be written in the form5 - √3 = p/qor 5 - p/q = √3It implies root3 is a rational number [Since 5 - p/q are rationals]But this contradicts to the fact that √3 is irrational. Hence our supposition was wrong. Therefore 5 - √3 is irrational. | |
