Issolvi (5/2+3/2)^2-4/frac{15{2}}

$$\frac { ( \frac { 5 } { 2 } + \frac { 3 } { 2 } ) ^ { 2 } - 4 } { \frac { 15 } { 2 } }$$

Evalwa

$$\frac{8}{5}=1.6$$

Passi tas-Soluzzjonijiet

Żid \frac{5}{2} u \frac{3}{2} biex tikseb 4.

$$\frac{4^{2}-4}{\frac{15}{2}}$$

Ikkalkula 4 bil-power ta' 2 u tikseb 16.

$$\frac{16-4}{\frac{15}{2}}$$

Naqqas 4 minn 16 biex tikseb 12.

$$\frac{12}{\frac{15}{2}}$$

Iddividi 12 b'\frac{15}{2} billi timmultiplika 12 bir-reċiproku ta' \frac{15}{2}.

$$12\times \frac{2}{15}$$

Immultiplika 12 u \frac{2}{15} biex tikseb \frac{8}{5}.

$$\frac{8}{5}$$

Fattur

$$\frac{2 ^ {3}}{5} = 1\frac{3}{5} = 1.6$$
