Hello students, in this question we have to find the smallest number out of the given four options.
00:09
So for finding the smallest number, first we should be clear about the powers and the number line.
00:16
So we know that, so this is a number line, here it is 0, in this side the negative numbers will be coming, that is minus 2, minus 3, minus 1, minus 2, minus 3 and minus 4.
00:33
On the right hand side, it is 1, 2, that is plus 1, plus 2, plus 3, plus 4.
00:41
So if we take 0 as the center, then on the right side the number system will be increasing and if we move towards left side, then the values are decreasing.
00:58
That means here minus 4 is a smaller number than minus 1.
01:06
So in this case, four numbers are given, let the option a is 3 .8 into 10 power 7, here b is 3 .8, c is 3 .8 into 10 power minus 18 and d it is 3 .8 into 10 power 15.
01:28
Let us represent these numbers with a number line.
01:30
This is 3 .8 into 10 power 0.
01:38
So anything power 0 will become 1, so it is 3 .8...
