Answer:
Step-by-step explanation:
When multiplying fractions, you multiply the numerators together and denominators together. This means that the problem above can be rewritten as, 
. Then, multiply this out to get 
. However, this fraction can be simplified by dividing the numerator and denominator by 2. This gives the final answer, .

9.6 months that is how long the investment lasted.
Answer:Your left hand side evaluates to:
m+(−1)mn+(−1)m+(−1)mnp
and your right hand side evaluates to:
m+(−1)mn+(−1)m+np
After eliminating the common terms:
m+(−1)mn from both sides, we are left with showing:
(−1)m+(−1)mnp=(−1)m+np
If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:
(−1)(−1)mn=(−1)n.
It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:
(−1)(−1)mn=(−1)−n=1(−1)n
Multiplying both sides by (−1)n then yields:
1=(−1)2n=[(−1)n]2 which is always true, no matter what n is
Answer:
Area of circle is 
Step-by-step explanation:
Formula for circumference of circle is given as,
Given that C = 15 n cm,
Substituting the value,
Solving above equation for r, divide both side by 
Simplifying,
Formula for area of circle is given as,
Substituting the value of r,
Squaring the parenthesis,
Cancelling out the common term,
Therefore, area of circle in terms of n is
