Answer:

So we got:

$\left(m^{\frac{2}{3}}n^{\frac{-1}{3}}\right)^6$

$m^4\left(n^{\frac{-1}{3}}\right)^6\\$

More attention for $(n^{\frac{-1}{3}}\right))^6\\$

$n^{-2}$

$\frac{1}{n^2}$

Join:

$m^4\frac{1}{n^2}$

$\frac{1\cdot \:m^4}{n^2}\\\frac{m^4}{n^2}$

Therefore, the answer is $\frac{m^4}{n^2}$ , letter A

Gannon has deposited $742 in a savings account that earns interest at a rate of 3.4% compounded monthly. What will the account b

marta [7]

Firstly, solve the effective annual interest (ieff) with the equation,

ieff = (1 + i/m)^m -1

where i is the interest rate and m is the number of times the interest is compounded in a year. In this problem, m is 12

Substituting the values,
ieff = (1 + 0.034/12)^12 - 1 =0.03453

To solve for the future (F) amount of the present investment (P),

F = P x (1 + ieff)^n

where n is number of years.

F = ($742) x (1 + 0.03453)^15

Thus, the answer is $1234.76.
