5. Check whether6 can end with the digit for any natural number n.รณExplain why 7x 11 x 13+13 and 7x6*4 3 21-5 are composite numbers. |
|
Answer» A composite number is a positive integer that has a factor other than 1 and itself. Now considering your numbers, 7×11×13+13 may be written as, 13x{(7x11) + 1} i.e. 13x(78). So other than 1 and the number itself, 13 and 78 are also the factors of the number. Further, 78=39x2. So, 39 and 2 are also it's factors. So this number is definitely not prime. Hence its composite number. Similarly, 7×6×5×4×3×2×1+5 can be written as 5x{(7x6x4x3x2x1)+1}, i.e. 5x(1009). So, other than the number and 1, it have 5 and 1009 as it's factors too. So it is also a composite number. Like my answer if you find it useful! |

binaryfissionWhy binary fissicn and budding are included under sexual reproduction. Arebudding faster processes of reproduction when compared to sexual reproduction? Justify |
|
Answer» Binary fission and budding are the modes of asexual reproduction. They are considered to be faster processes when compared to sexual reproduction.*Asexual reproduction occur in small, simple unicellular or sometimes in simple multicellular organisms taking less time.*Asexual reproduction requires less time as it involves single parent. Sexual reproduction requires more time as it involves release of gametes from both the parents of opposite sex. Gametes formed by parents of opposite sex fuse and undrgo fertilisation process only under favourable conditions. So, sexual reproduction takes more time comparitively. |
