Réitigh 7164=P[(1+5/100)^2-1]

$$7164 = P [ ( 1 + \frac { 5 } { 100 } ) ^ { 2 } - 1 ]$$

Réitigh do P.

$$P = \frac{2865600}{41} = 69892\frac{28}{41} \approx 69892.682926829$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Laghdaigh an codán \frac{5}{100} chuig na téarmaí is ísle trí 5 a bhaint agus a chealú.

$$7164=P\left(\left(1+\frac{1}{20}\right)^{2}-1\right)$$

Suimigh 1 agus \frac{1}{20} chun \frac{21}{20} a fháil.

$$7164=P\left(\left(\frac{21}{20}\right)^{2}-1\right)$$

Ríomh cumhacht \frac{21}{20} de 2 agus faigh \frac{441}{400}.

$$7164=P\left(\frac{441}{400}-1\right)$$

Dealaigh 1 ó \frac{441}{400} chun \frac{41}{400} a fháil.

$$7164=P\times \frac{41}{400}$$

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$P\times \frac{41}{400}=7164$$

Iolraigh an dá thaobh faoi \frac{400}{41}, an deilín de \frac{41}{400}.

$$P=7164\times \frac{400}{41}$$

Méadaigh 7164 agus \frac{400}{41} chun \frac{2865600}{41} a fháil.

$$P=\frac{2865600}{41}$$
