Unless there's a clearer copy of it somewhere, I doubt it has any meaning. Last edited by skipjack; February 28th, 2017 at 03:32 AM.

The first is a sum of powers of 2, but I cannot read the powers. 5!= 5(4)(3)(2)(1) = 120. The last term in the numerator is a power of 7, but again I cannot read the power. In the denominator, the limit, as x goes to 0 of $\displaystyle \frac{\sin(x)}{x}$ is "1" and $\displaystyle i^4$ is also "1". $\displaystyle \cos\left(\frac{3\pi}{4}\right) = -\frac{\sqrt{2}}{2}$. The last is $\displaystyle \frac{\sqrt{3}}{2}$ which is about 0.8660. I strongly suspect that this is not supposed to be equal to any specific number but just an arbitrary combination of math symbols. Last edited by skipjack; February 28th, 2017 at 04:03 AM.

There is a picture of this online. My teacher bought a shirt that has this on it and we have to solve it to get points. Can someone explain what it means in detail please.?

Your teacher wants YOUR explanation, not ours...

 February 28th, 2017, 05:53 AM #10 Global Moderator   Joined: Dec 2006 Posts: 21,016 Thanks: 2250 I think the expression inside the cube root is as shown below: $$\dfrac{-\left(\displaystyle \sum_{n = 1}^{15}e^{\large\ln n}\right)\Bigg({\Large5!}\Bigg) {\Bigg(}{\Large7}^{{\Large\ln}_{ \large7}\large120}{\Bigg)}}{\displaystyle \left(\lim_{x \to 0}\frac{\sin x}{x}\right){\bigg(}i^{\large4}{\bigg)} \left(\cos \frac{3\pi}{4}\right) \left(\frac{2}{\sqrt2}\right)}$$ which would make the original expression evaluate to 120%. (The expression uses $\log_7$, but that means the same as the $\ln_7$ given above.) However, the $\sqrt2$ is hard to read and might be $\sqrt3$.
