Answer:
Step-by-step explanation:
The given expression has the first term n=1, so exponent = n-1 = 0
Similarly, for the second term n = 2, n-1 = 1
These exponents eliminate options 2 and 4.
Furthermore, the base is a fraction of 1/2, which applies to options 1 and 2 only.
The only viable option left that satisfies all conditions is option 1, which has exponents 0 and 1, with a base of (1/2).

Answer:
15 meters
Step-by-step explanation:
that means the leg lengths of the triangle are 12 m and 9 m
use Pythagorean theorem:
D = root (12^2 + 9^2) = root( 144 + 81) = root(225) = 15 m
