Answer:
- 2⁻⁶
Step-by-step explanation:
To simplify this we have to know the following rules.
(i) (xᵃ)ᵇ = xᵃᵇ
(ii) 1/xᵃ = x⁻ᵃ
Given: 
= 
=
=
[using (i)]
=
[using (ii)]
Hence, the simplified form would be: 
Answer:
The number of test required is: 55
Explanation:
Using combination formula:
n!/x!(n-x)!
= 11!/2!(9)!
= 55
Answer:
d. x = 5
Step-by-step explanation:
Chords that subtend congruent arcs are congruent.
<h3>Setup</h3>
Chord lengths are the same:
AB = CD
16x -2 = 14x +8
<h3>Solution</h3>
2x = 10 . . . . . . add 2-14x
x = 5 . . . . . . . . divide by 2
