Susah tau jawab grade 5! 🙁

Jawaban:

$\chi = {3}^{ - 3}$

$\eta = {5}^{ - 2}$

$\chi + \eta = \dots$

______________

$\chi = {3}^{ - 3}$

$\chi = \frac{1}{ {3}^{3} }$

$\chi = \frac{1}{(3 \times 3 \times3 )}$

$\chi = \frac{1}{27}$

$\eta = {5}^{ - 2}$

$\eta = \frac{1}{ {5}^{2} }$

$\eta = \frac{1}{(5 \times 5)}$

$\eta = \frac{1}{25}$

___________

Maka :

$\chi + \eta = \dots$

$\sf \frac{1}{27} + \frac{1}{25}$

$\sf \frac{25}{675} + \frac{27}{675}$

$\sf \frac{25 + 27}{675}$

$\sf = \frac{52}{675}$
