Answer 2

Answer:

Step-by-step explanation:

5* (2⁰ + 2¹ + 2 ²+ 2³+ ........+ 2¹⁰)

Sum of geometric series = $a*\frac{r^{n}-1}{r-1}$

a -> first term = 1

r- ratio = 2

n --> number of terms = 11

5* (2⁰ + 2¹ + 2 ²+ 2³+ ........+ 2¹⁰)=

 $5*[1*\frac{2^{11}-1}{2-1}]\\\\=5 *[1*(2048-1)]\\\\= 5 * 2047\\= 10235$
