Verified answer
1.) 4/5 - (8/9 - 7/3) =
= 4/5 - (8/9 - 21/9)
= 4/5 - (-13/9)
= 4/5 + 13/9
= 36/45 + 65/45
= 101/45
= 2 11/45
2.) 8² × 4² + 25 =
= 64 × 16 + 25
= 1.024 + 25
= 1.049

Penjelasan dengan langkah-langkah:
[tex] \frac{4}{5} - \frac{8}{9} - \frac{7}{3} \\ = \frac{4 \times 9}{5 \times 9} - \frac{8 \times 5}{9 \times 5} - \frac{7 \times 15}{3 \times 15} \\ = \frac{36}{45} - ( \frac{40}{45} - \frac{105}{45} )\\ = - \frac{36}{45} - -\frac {65}{45} = \frac {101}{45} = - 2 \frac{11}{45} [/tex]
[tex] {8}^{2} \times {4}^{2} + 25 \\ = (8 \times 8) \times (4\times 4) + 25 \\ = 64 \times 16 + 25 \\ = 1.049[/tex]
