Hello :
<span>√3 = 3^(1/2)
243 = 3^(5)
subsct in :
</span><span>243√3 =3^a
</span> 3^(5)×3^(1/2) = 3^a
3^(5+1/2) = 3^a
a = 5+1/2 = 11/2
a = 5.5
False, counter example is 15
First you need to change the fractions to have the same denominator.
9 1/2 = 9 2/4 + 7 3/4
Then you just add across and simplify.
9 2/4 + 7 3/4 = 16 5/4 = 17 1/4.
You should get 17 1/4. Good luck!
The two points have the same y value, so it is a horizontal line. Between 5 and 10, the distance is 5.
