anonymous · Answer

How about this one? $$\left( \sqrt{8.01\times25.01} \right)\div1.99$$

callisto · Answer

$$\sqrt{8.01\times 25.01} = \sqrt{200.3301} $$Do you mind using your calculator a little bit?

anonymous · Answer

No. I am not allowed to use a calculator in this question.

inkyvoyd · Answer

round to sqrt(8*25), then it becomes 50sqrt2. In other words, about 50*1.414

inkyvoyd · Answer

1 significant figure just means one digit, i'm pretty sure.

inkyvoyd · Answer

*10sqrt(2)

inkyvoyd · Answer

so, the number is around 14

lgbasallote · Answer

@inkyvoyd i think you mean 10 sqrt 2 yes? because the sqrt of 25 = 5 and the sqrt of 8 is 2 sqrt 2

callisto · Answer

1 significant figure here means the first digit you see.. i think so it should be 10...
