Answer:

\frac{1}{16}

Step-by-step explanation:

With a negative fractional exponent place a 1 over the positive value

\frac{1}{ {8}^{ \frac{4}{3} } }

rewrite 8 as

( {2}^{3} ) ^{ \frac{4}{3} }

apply the power rule and multiply the exponents.

cancel the common factor of 3

rewrite the expression

\frac{1}{ {2}^{4} }

raise 2 to the power of 4 which =16

so the answer is

\frac{1}{16}

Answer:

Hi there

The formula is

A=p (1+r)^t

A future value

P present value

R interest rate

T time

A) A=2,000×(1+0.04)^(3)=2,249.728

B) A=2,000×(1+0.04)^(18)=4,051.63

C) 2500=2000 (1+0.04)^t

Solve for t

T=log(2,500÷2,000)÷log(1+0.04)

T=5.7 years

D) t=log(3,000÷2,000)÷log(1+0.04)

t=10.3 years

Hope it helps
