¿Cuál es el capital que colocado al 6% quincenal<br> genera en 2 meses un monto de S/. 7200?
Zinaida [17]

Answer:

$27428.57

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

P = Po * (1 + r)^(t)

Where P is the final value, Po is the inicial value, r is the rate of interest, t is the time.

With r = 0.06, t = 4 (The rate is for every 15 days, and the time is 2 months, so we have that 2 months = 4 periods of 15 days) and P = Po + 7200, we have:

Po + 7200 = Po * (1 + 0.06)^4

Po + 7200 = Po * 1.2625

Po * 0.2625 = 7200

Po = 7200 / 0.2625 = $27428.57

Simplify the following expression. 3^11/5 divided by 3^-9/5
san4es73 [151]

Answer:

Answer is 81.

Step-by-step explanation:

Given two expressions are 3^{\frac{11}{5} } and 3^{-\frac{9}{5} }

Now we divide first expression by the second.

\frac{3^{\frac{11}{5} }}{3^{-\frac{9}{5} } }

3^{\frac{11}{5} }.3^{\frac{9}{5} }

3^{\frac{11}{5}+\frac{9}{5}} = 3^{\frac{20}{5} }=3^{4}=81

Therefore 81 is the answer.
