Simplify the expression. Write your answer as a power.<br><br> (−5/7)^8⋅(−5/7)^9
dem82 [27]

Answer: (-\frac{5}{7})^{17}

Step-by-step explanation:

The expression can be simplified by applying the a properties of exponents, specifically the Product of powers, which states that:

(b^a)(b^c)=b^{(a+c)

Where b is the base and a and c are exponents.

 Then simplify it by rewriting the base (-\frac{5}{7}) and adding the exponents of the expression (8 and 9).

You will get the expression simplified and written as a power:

(-\frac{5}{7})^8(-\frac{5}{7})^9=(-\frac{5}{7})^{(8+9)}=(-\frac{5}{7})^{17}

A shark can chase prey about 30 miles per hour. What is this rate in miles per minute?
Pavlova-9 [17]

Solution :

Give that a shark can chase prey about 30 miles per hour.

1 hour = 60 minute

by using unitary method, we will convert miles per hour into miles per minute

in 60 minutes the shark can chase the prey 30 miles

In 1 minute the shark can chase \frac{30}{60}  miles = \frac {1}{2} miles= 0.5 miles

Hence the shark can chase the prey about 0.5 miles per minute.

For each logarithmic equation, write an equivalent equation in exponential form
Montano1993 [528]

Answer:

  • loga b = c             ⇔   a^c = b

<u>Apply the property above:</u>

  • 1.  ln 618 = p   ⇔ e^p = 618
  • 2. ln q = 2       ⇔ e^2 = q
  • 3. ln 100 = t     ⇔  e^t = 100
  • 4. ln (e^3) = 3  ⇔  e^3 = e^3
