1. ~Eksponen

Soal

{sf{ sqrt{32} + sqrt{50} = ... }}

Penyelesaian

{sf{ = sqrt{32} + sqrt{50}}}

{sf{ =( sqrt{16} times sqrt{2} ) + ( sqrt{25} times sqrt{2} )}}

{sf{ = (4 times sqrt{2} ) + (5 times sqrt{2} )}}

{sf{ = 4 sqrt{2} + 5 sqrt{2}}}

{sf{ = (4 + 5) sqrt{2}}}

{boxed{sf{blue{ = 9 sqrt{2}}}}}

Kesimpulan

Jadi, Bentuk Sederhanan dari √32 + √50 adalah 9√2

Soal

{sf{ frac{1}{5} + frac{1}{4} times frac{2}{3} = ...}}

Penyelesaian

{sf{ = frac{1}{5} + frac{1}{4} times frac{2}{3}}}

{sf{ = frac{1}{5} + ( frac{1}{4} times frac{2}{3} )}}

{sf{ = frac{1}{5} + ( frac{1 times 2}{4 times 3} )}}

{sf{ = frac{1}{5} + frac{2}{12}}}

{sf{ = (frac{1 times 12}{ 5times 12} ) + ( frac{2 times 5}{12 times 5} )}}

{sf{ = frac{12}{60} + frac{10}{60}}}

{sf{ = frac{12 + 10}{60}}}

{sf{ = frac{22}{ 10}}}

{sf{ = frac{22 div 2}{10 div 2}}}

{boxed{sf{blue{ = frac{11}{5}}}}}

Kesimpulan

Jadi, Bentuk Sederhana dari ⅕ + ¼ × ⅔ adalah 11/5

1. sf sqrt{32} + tt sqrt{50}

Penyelesaian :

=> sf sqrt{32} + sf sqrt{50}

=> ( sf sqrt{16} × sf sqrt{2} ) + ( sf sqrt{25} × sf sqrt{2} )

=> (4 times sf sqrt{2} ) + (5 times sf sqrt{2} )

=> 4 sf sqrt{2} + 5 sf sqrt{2}

=> (4 + 5) sf sqrt{2}

=> {boxed{red{sf{9sqrt{2}}}}}

2. sf frac{1}{5} + sf frac{1}{4} × sf frac{2}{3}

Penyelesaian :

=> sf frac{1}{5} + sf frac{1×2}{4×3}

=> sf frac{1}{5} + sf frac{2}{12}

=> sf frac{12+10}{60}

=> sf frac{22}{60}

=> {boxed{red{sf{frac{11}{5}}}}}
