Answer:
9) 4
10) p¹⁵/q⁹
Step-by-step explanation:
9)
As per the law of indices, (xᵃ)ᵇ=xᵃᵇ.
So divide 8 by 2 to get 4
10)
p(p⁻⁷q³)⁻²q⁻³
p(p¹⁴q⁻⁶)q⁻³ <em>(because (xᵃ)ᵇ=xᵃᵇ)</em>
pq⁻³(p¹⁴q⁻⁶)
p¹⁵q⁻⁹
p¹⁵/q⁹ <em>(because x⁻ᵃ =1 /xᵃ)</em>

The answer to your question is below
Step-by-step explanation:
See the picture, please
In the first picture, we notice the initial amount of brownies (7/10), 7 brownies in a pan for 10 brownies.
After Tyreese bought 2/5 (7/10 - 2/5 = 3/10) there are 3 brownies left.
So in the picture, we notice only 3 brownies in a pan for 3 brownies.
If she rides her bike 18 km per hour
then it will take 4 hours to travel 72 km (72÷18)
the answer is 4
Answer:
= c^4 d^8 a^2
Step-by-step explanation:
Apply exponent rule: aa= a^2
= c^3 da^2 cd^7
= c^4 da^2 d^7
= c^4 d^8 a^2
