Step-by-step explanation:
1. The factors of 1936 is,
1936=2×2×2×2×11×11
Take square root both sides,
1936=2×2×2×2×11×11
=24×112
=((2)2×11)2
=4×11
=44
Therefore, the square root of 1936 is 44.
2. The square root of 1681 is 41.
3. The square root of 56.25 is 7.5.
4.The required solution of the problem is
Let find the LCM of the given numbers i.e. 8,12,15and20
That is,
2×2×2×5×3=120
But, 2,3,5 are not in pair so
multiply these with LCM
=120×3×5×2
=3600
Therefore there are 3600 numbers.
