Q.

Tentukan hasil dari operasi dibawah ini
[tex]4 \frac{2}{5} \times \frac{12}{45} \times \cos( {45}^{0} ) = ......[/tex]

​

Answer 1

Jawaban:

[tex] \frac{44}{75} \sqrt{2} [/tex]

Penjelasan dengan langkah-langkah:

cos(45°) = √2/2

..

[tex]4 \frac{2}{5} \times \frac{12}{45} \times \frac{ \sqrt{2} }{2} [/tex]

[tex] = \frac{22}{5} \times \frac{4}{15} \times \frac{ \sqrt{2} }{2} [/tex]

[tex] = \frac{88}{75} \times \frac{ \sqrt{2} }{2} [/tex]

[tex] = \frac{44}{75} \times \frac{ \sqrt{2} }{1} [/tex]

[tex] = \frac{44}{75} \sqrt{2} [/tex]
