Question

evaluate :
1/underoot2 ×100​

Answer 1

$= \frac{1}{ \sqrt{2} } \times 100 \\ = \frac{100}{ \sqrt{2} } \\ = \frac{100}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ = \frac{100 \sqrt{2} }{2} \\ = 50 \sqrt{2}$

Answer 2

Step-by-step explanation:

The numerals 1, 0, and 0 are adjacent to each other. This indicates this is a single number, with three digits, reading from left to right. There is no sub numeral, so the assumption is that this is base ten. This means we have 1 in the hundreds place, zero in the tens place, and zero in the ones place. So in total, one hundred.

Then there is a space, with no operator in it. Following this, there is a digit, a diagonal line, and another digit. This indicates a division operation, in this case one divided by two. However, this configuration can also denote a fraction, in this case, one half (which is, after all, the value of one divided by two). And when we have a number, a space, and a fraction, then the operation used here is addition, more, it is treated as though the pair are in parentheses. One hundred and a half.

Expressed in decimal form, this would also be 100.5

It would not be 1001 divided by two. It would not be 100 times 1/2. It would not be 1001 base two.

Just a hundred and a half, or 100.5
