Answer 1

Verified answer

sifat eksponen yang digunakan :

[tex] \frac{ {x}^{n} }{ {x}^{m} } = {x}^{n - m} [/tex]

[tex] {x}^{ - n} = \frac{1}{ {x}^{n} } [/tex]

_____________________________________

[tex] = {3}^{4} \div {3}^{7} [/tex]

[tex] = {3}^{4 - 7} [/tex]

[tex] = {3}^{ - 3} [/tex]

[tex] = \frac{1}{ {3}^{3} } [/tex]

_____________________________________

[tex] = \frac{3}{243} [/tex]

[tex] = \frac{ {3}^{1} }{ {3}^{5} } [/tex]

[tex] = {3}^{1 - 5} [/tex]

[tex] = {3}^{ - 4} [/tex]

[tex] = \frac{1}{ {3}^{4} } [/tex]

_____________________________________

[tex] = {5}^{2} - {5}^{ - 2} [/tex]

[tex] = {5}^{2} - \frac{1}{ {5}^{2} } [/tex]

[tex] = \frac{ {5}^{4} }{ {5}^{2} } - \frac{1}{ {5}^{2} } [/tex]

[tex] = \frac{ {5}^{4} - 1 }{ {5}^{2} } [/tex]

Answer 2

Jawaban:

3^4 ÷ 3^7

3^4-7

3^-3

1/3³

1/3×3×3

1/27

3/243

3÷3/243÷3

1/81

5² - 5-²

5×5 - 1/5²

25 - 1/25

[tex] \frac{25}{1} - \frac{1}{25} = \frac{625}{25} - \frac{1}{25} = \frac{624}{25} [/tex]

Salah Koreksi.
