Answer:
Step-by-step explanation:
5* (2⁰ + 2¹ + 2 ²+ 2³+ ........+ 2¹⁰)
Sum of geometric series = [tex]a*\frac{r^{n}-1}{r-1}[/tex]
a -> first term = 1
r- ratio = 2
n --> number of terms = 11
5* (2⁰ + 2¹ + 2 ²+ 2³+ ........+ 2¹⁰)=
[tex]5*[1*\frac{2^{11}-1}{2-1}]\\\\=5 *[1*(2048-1)]\\\\= 5 * 2047\\= 10235[/tex]
