Last and not least, last question guys.

The answere to the last question is never.In order for a triangle to be equilateral, all corners have to be equal.A triangle's corner sum cant be over 180°.So as we all know, a right triangle has one right corner.If a corner is right, then, all corners can't be equal(because 90 is the half of 180).So the triangle can't be equilateral.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
