Question

why 3*4*5*6*7+7 is a composite number?​

Answer 1

Step-by-step explanation:

Starting February 18, 1946, a group of ratings at the Royal Indian Navy mutinied in Bombay. The mutiny soon spread to all units of the Royal Indian Navy: ships at anchor, shore establishments, ships on the high seas. The mutiny was brutally suppressed by the British with complicity of icons of India’s freedom struggle: Gandhi, Patel and Nehru. The import of the mutiny may be judged from an extract of a letter written by P.V. Chuckraborty, former Chief Justice of Calcutta High Court, on March 30 1976: "When I was acting as Governor of West Bengal in 1956, Lord Clement Attlee, who as the British Prime Minister in post war years was responsible for India’s freedom, visited India and stayed in Raj Bhavan Calcutta for two days`85 I put it straight to him like this: ‘The Quit India Movement of Gandhi practically died out long before 1947 and there was nothing in the Indian situation at that time, which made it necessary for the British to leave India in a hurry. Why then did they do so?’ In reply Attlee cited several reasons, the most important of which were the INA activities of Netaji Subhas Chandra Bose, which weakened the very foundation of the British Empire in India, and the RIN Mutiny which made the British realise that the Indian armed forces could no longer be trusted to prop up the British. When asked about the extent to which the British decision to quit India was influenced by Mahatma Gandhi’s 1942 movement, Attlee’s lips widened in smile of disdain and he uttered, slowly, ‘Minimal’."

Answer 2

we have

$3 \times 5 \times 7 + 7 = 105 + 7 = 112$

Now,

$112 = 2 \times 2 \times 2 \times 7 = 2 {}^{4} \times 7$

So, it is the product of prime factors 2 and 7 i.e., it has more than two factor Hence, it is composite number=
