Answer» Answer: p^2= 2q^2 p^2 is a multiple of 2 hence, p is a multiple of 2 let P= 2m (2m)^2 = (√2q)^2 4m^2 = 2q^2 2m^2= q^2 q^2 is a multiple of 2 q is a multiple of 2 it is against our assumptions and hence it is proved that √2 is irrational. Let's take that ✓3 is a rational number where √3 = p/q and are in their lowest terms. p^2= 3q^2 p^2 is a multiple of 3 hence, p is a multiple of 3 let P= 2m (3m)^2 = (√3q)^2 9m^2 = 3q^2 3m^2= q^2 q^2 is a multiple of 3 q is a multiple of 3 it is against our assumptions and hence it is proved that √3 is irrational.
p^2= 5q^2 p^2 is a multiple of 5 hence, p is a multiple of 5 let P= 5m (5m)^2 = (√5q)^2 25m^2 = 5q^2 5m^2= q^2 q^2 is a multiple of 5 q is a multiple of 5 it is against our assumptions and hence it is proved that √5 is irrational.
p^2= 7q^2 p^2 is a multiple of 7 hence, p is a multiple of 7 let P= 7m (7m)^2 = (√7q)^2 49m^2 = 7q^2 7m^2= q^2 q^2 is a multiple of 7 q is a multiple of 7 it is against our assumptions and hence it is proved that √7 is irrational. Above it is clearly proved that √2 , √3 , √5 and √7 are irrational. "The SUM of irrational numbers will always be irrational. " hence it is proved that the sum of √2 , √3 , √5 and √7 will be an irrational number. hope it helps! please MARK as brainliest! ♥ |

By selling 5 bananas a rupees a man lost 20%.if he had 12 dozen bananas with him what was the c.p.and s.p. of the bananas |
Answer» Given:By selling 5 bananas a rupees a man lost 20%. If he had 12 dozen bananas with him To find:What was the c.p.and s.p. of the bananas? Solution:S.P. of 5 bananas = Re. 1 So, S.P. of 1 banana = Rs. ∴ C.P. of 1 banana is, = = = = We know, ∴ 12 dozen bananas = 12 × 12 = 144 bananas Now, C.P. of 144 bananas = C.P. of 1 banana × 144 = and S.P. of 144 bananas = S.P. of 1 banana × 144 = Thus, the C.P. of the bananas is Rs. 36 and the S.P. of the bananas is Rs. 28.8. --------------------------------------------------------------------------- Also VIEW:SP of 6 bananas is the same as the CP of 5 bananas find the gain or loss per cent 4 dozen bananas were bought at the rate of 15 per dozen and SOLD at the rate of 2 per banana. Profit or loss is (1) 60, loss (2) 96, profit (3) 7156, loss (4) 36, profit The Cost price of 10 bananas is equal to the selling price of 12 bananas find the loss per cent |
