<span> (8^ -2)(4^4)(16^ -1)
</span>
<span>a^-x=(1/a^x)
</span>
<span> (4^4)/((8^2)(16))
"NOTE" </span><span>16^1=16
</span>
<span>4^4=256
8^2=64
256/((64)(16))=1/4
</span>
<span>convert 1/4 to a power of two
</span>
<span>(4) is 2
1/4=1/(2^2)
</span>
<span>1^2=1
(1/2)^2=(1/4)
</span>
<span>1/2 to the power of 2 is the answer
It would look like this
1/2²</span>
-10 and 2
-10 x 2 = -20
-10 + 2 = -8
Answer is 42. Don't listen to the guy that said it's 168. I did the test and it marked it wrong.
Answer:
The answer will be 7L/100km.
Step-by-step explanation:
The fuel consumption rate is already given for the first 100 km. So, the next 500 km will be 100km to 600km. You have to find the slope of the line during this travel. If you observe, the fuel lowers from 40 litres to 5 litres in this 500km journey. That means, 35 litres were used for 500km. Divide both with 5. That gives 7litres per 100km.
