Answer:

√3 + 1

Step-by-step explanation:

Step below are self-explanatory

2/(√3−1)=
2×(√3 + 1)/(√3 - 1)×(√3 + 1) = <em>multiplied both sides by √3 + 1</em>
2×(√3 + 1)/(√3² - 1²)= <em> used (a+b)(a-b)= a² - b² formula</em>
2×(√3 + 1)/(3 - 1)=
2×(√3 + 1)/2= <em>cancelled like terms</em>
√3 + 1

PLease help me ,really need help with explanation

Check the picture below.

volume wise, we know the smaller pyramid is 1/8 th of the whole pyramid, so the volume of the whole pyramid must be 8/8 th.

Now, if we take off 1/8 th of the volume of whole pyramid, what the whole pyramid is left with is 7/8 th of its total volume, and that 7/8 th is the truncated part, because the 1/8 we chopped off from it, is the volume of the tiny pyramid atop.

Now, what's the ratio of the tiny pyramid to the truncated bottom?

$\stackrel{\textit{\Large Volumes}}{\cfrac{\textit{small pyramid}}{\textit{frustum}}\implies \cfrac{~~\frac{1}{8}whole ~~}{\frac{7}{8}whole}}\implies \cfrac{~~\frac{1}{8} ~~}{\frac{7}{8}}\implies \cfrac{1}{8}\cdot \cfrac{8}{7}\implies \cfrac{1}{7}$
