Patterns to find the square of some
standrad numbers, Pythagorean triplets
- Sattvaj here Is it compulsory that the difference between the 2 bigger no.s in Pythagorean triplets is 2? 18,80 and 82, there is a difference of 2 between 80 and 82 so is it there in all no.s or there can be a smaller/bigger difference?
- 1967 perfect square
- What will be the ones digits of the square of the number 1145
- Find the square of the number 82 using the property (a + b)2 = a2 + b2 + 2ab.
- Find the square of the number (-25), using the identity (a + b)2 = a2 + b2 + 2ab.
- Using the given pattern, find the missing numbers. 12 + 22 + 22 = 32 22 + 32 + 62 = 72 32 + 42 + __ = 132 42 + 52 + 202 = __2 52 + 62 + __ = 312 62 + __ + 422 = 432
- Observe the following pattern and find the missing numbers. 112 = 121 1012 = _ _ _ _ _ 101012 = 102030201 10101012 = 1_ _ _ _ _4_ _ _ _ _1 1010101012 = _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
- Observe the following pattern and write the missing numbers. 12 = 1 112 = 121 1112 = 12321 11112 = ________ 111112 = _________
- Observe the following pattern: 11 × 13 = (12 - 1) × (12 + 1) = 122 - 1 13 × 15 = (14 - 1) × (14 + 1) = 142 - 1 15 × 17 = (16 - 1) × (16 + 1) = 162 - 1 Using this pattern, find (i) 19 × 21 (ii) 29 × 31
- Observe the following pattern and find the missing numbers. 72 = 49 672 = 4489 6672 = 444889 66672 = 44448889 666672 = ___________ 6666672 = ____________
