Answer:

Arc length is 12436.8m

Step-by-step explanation:

arc length = $\frac{M degree}{360degree}$ * πD

where M is the angle measure of the arc

and D is the diameter

considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees

$\frac{180}{360}$ * π * 7917.5 = 12436.8m

$7^x+49^{ \frac{x}{2} }=2\cdot \sqrt[5]{343} \\ \\ 7^x+(7^2)^{ \frac{x}{2} }=2\cdot \sqrt[5]{7^3} \\ \\7^x+ 7^x=2\cdot 7^{ \frac{3}{5} } \\\\ 2 \cdot 7^x=2\cdot 7^{ \frac{3}{5} } \ \ \ | \div2 \\ \\ 7^x=7^{ \frac{3}{5} } \\ \\ x= \frac{3}{5}$
