-8 is the answer to your question
Remember property of exponents
![(x^m)(x^n)=x^{m+n}](https://tex.z-dn.net/?f=%28x%5Em%29%28x%5En%29%3Dx%5E%7Bm%2Bn%7D)
add exponents of same base
ok so
50,000 is 5 times 10^4
so
50000 times 10^15=
5 times 10^4 times 10^15=
5 times
![10^{4+15}](https://tex.z-dn.net/?f=10%5E%7B4%2B15%7D)
=
5 times 10^19
<span>This polygon is composed of a right triangle and <span>a parallelogram.
The area of right angle :
![A_\Delta=\frac{1}{2}\cdot15\cdot8=\frac{1}{2}\cdot120=\boxed{60\ (cm^2)}](https://tex.z-dn.net/?f=A_%5CDelta%3D%5Cfrac%7B1%7D%7B2%7D%5Ccdot15%5Ccdot8%3D%5Cfrac%7B1%7D%7B2%7D%5Ccdot120%3D%5Cboxed%7B60%5C%20%28cm%5E2%29%7D)
The area of the </span></span><span>parallelogram</span>:
![A_P=15\cdot(13-8)=15\cdot5=\boxed{75\ (cm^2)}](https://tex.z-dn.net/?f=A_P%3D15%5Ccdot%2813-8%29%3D15%5Ccdot5%3D%5Cboxed%7B75%5C%20%28cm%5E2%29%7D)
The area of the polygon is equal:
![A=A_\Delta+A_P](https://tex.z-dn.net/?f=A%3DA_%5CDelta%2BA_P)
Therefore, the answer is:
