Let us assume that 1/2+root 3 is rational . So 1/2+root 3 = a/b where a and b are irrationals. since rhs is a rational number root 3 should be also rational .

The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486

<h3>Compound interest</h3>

Compound interest is given by:

$A=P(1 + \frac{r}{n} )^{nt}$

where t is the period, r is the rate, P is the initial amount, A is the final amount and n is the times compounded.

Given P = 2950, r = 0.084, n = 4, t = 2, hence:

$A=2950(1+\frac{0.084}{4} )^{4*2}\\\\A=\$3486\\\\For \ r=0.078, A=3742,t=2,n=1:\\\\3742=P(1+\frac{0.078}{1} )^{1*2}\\\\P=\$3220$

The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486
