Square root of 100/121

Mathematics

klasskru [66]3 years ago
7 0
Ah... good ol' square roots...

Whenever you take the square root of multiplication or division, you can do the square roots separately. So, we can write:

\sqrt{\frac{100}{121}} = \frac{\sqrt{100}}{\sqrt{121}}

This nifty truth allows us to easily find the answer:
\frac{\sqrt{100}}{\sqrt{121}} = \frac{10}{11}

All done!

Find the 52nd term of the following arithmetic sequence.<br> 17, 22, 27, 32, ...
rewona [7]

Answer:

17; 22; 27; 32

the terms increase by 5 each time

17 + 5 = 22 (the second term)

17 + 5 * 2 = 27 (third term)

So to get to the 52nd term, we have to add 5* 51 = 255 to 17

17 + 255 = 272
