The equivalent expression to
<span>(4p^-4q)^-2/10pq^-3
</span>=(4^-2p^(-4*-2)q^-2)/(10pq^-3)
=(4^-2p^8q^-2)/(10pq^-3)
=[p^8q^-2/16]/[10pq^-3]
=p^7q/160
Answer: C]<span>p^7q/160</span>
Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Match each equation with its solution set.
a2 − 9a + 14 = 0
a2 + 9a + 14 = 0
a2 + 3a − 10 = 0
a2 + 5a − 14 = 0
a2 − 5a − 14 = 0

Step-by-step explanation:
The number of books in her summer reading list is = 20
The number of books that has been read by Emma = 14
The percentage of books that has been read by Emma = 70%
But the percentage of books in Emma summer reading list = 100%
∴ The number of books in her reading list= ˣ
That is ;
70% = 14
100% = ˣ
Make ˣ the subject of formula,
ˣ = 100 × 14 / 70
ˣ = 20
