Answer:

x^{-28}*7^{-56}

Step-by-step explanation:

Firstly, you need to know that raising a fraction to a power raises both the top and the bottom to that power.

Second, a negative power on the top and bottom flips the fraction

Last, raising a power to a power multiplies the powers

So, \frac{7^{-8^{7}}}{x^{4^7}}=\frac{7^{-56}}{x^{28}}=\frac{1}{x^{28}*7^{56}}=x^{-28}*7^{-56}

Suppose that during one period extreme cold,the average daily temperature decreased 1 1/2 F each day. How many days did it take
Alenkasestr [34]

We have been given that during one period extreme cold, the average daily temperature decreased 1\frac{1}{2} degree F each day. We are asked to find number of days it will take for the temperature to decrease by 9 degree F.

First of all we will convert our mixed fraction into improper fraction.

1\frac{1}{2}=\frac{3}{2}

Now we will divide total temperature change (9) by average daily temperature change (\frac{3}{2}) to find number of days.

9\div\frac{3}{2}

Dividing a number by a fraction is same as multiplying the number by reciprocal of the fraction.

9\cdot\frac{2}{3}

3\cdot2=6

Therefore, it will take 6 days for the temperature to decrease by 9 degree F.
