10 + \frac{250}{π} + \frac{1500}{π ^{3}}

+1

Decimale

137.95477 \dots

Fasi della soluzione

\frac{10 ( π ^{3} + 25 ( π ^{2} + 6 ) )}{π ^{3}}

Espandi

π^{3} + 25 (π^{2} + 6) : π^{3} + 25 π^{2} + 150

= \frac{10 ( π ^{3} + 25 π ^{2} + 150 )}{π ^{3}}

Espandi

10 (π^{3} + 25 π^{2} + 150) : 10 π^{3} + 250 π^{2} + 1500

= \frac{10 π ^{3} + 250 π ^{2} + 1500}{π ^{3}}

Applica la regola delle frazioni:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{10 π ^{3} + 250 π ^{2} + 1500}{π ^{3}} = \frac{10 π ^{3}}{π ^{3}} + \frac{250 π ^{2}}{π ^{3}} + \frac{1500}{π ^{3}}

= \frac{10 π ^{3}}{π ^{3}} + \frac{250 π ^{2}}{π ^{3}} + \frac{1500}{π ^{3}}

Cancellare

\frac{10 π ^{3}}{π ^{3}} : 10

= 10 + \frac{250 π ^{2}}{π ^{3}} + \frac{1500}{π ^{3}}

Cancellare

\frac{250 π ^{2}}{π ^{3}} : \frac{250}{π}

= 10 + \frac{250}{π} + \frac{1500}{π ^{3}}
