tolong bantu jawab ya
[tex] {2}^{ - 2} + {2}^{ - 3} + {2}^{ - 4} = [/tex]
[tex] {2}^{ - 2} \times {2}^{ - 3} \times {2}^{ - 4} = [/tex]
[tex] {2}^{2} \times {3}^{2} \times 4 { - }^{1} = [/tex]

Nomor 1

[tex] {2}^{ - 2} + {2}^{ - 3} + {2}^{ - 4} \\ \\ = \frac{1}{ {2}^{2} } + \frac{1}{ {2}^{3} } + \frac{1}{ {2}^{4} } \\ \\ = \frac{1}{4} + \frac{1}{8} + \frac{1}{16} \\ \\ = \frac{4 + 2 + 1}{16} \\ \\ = \frac{7}{16} [/tex]

[tex] \\ [/tex]

Nomor 2

[tex] {2}^{ - 2} \times {2}^{ - 3} \times {2}^{ - 4} \\ = {2}^{ - 2 + ( - 3) + ( - 4)} \\ = { 2}^{ - 5 + ( - 4)} \\ = {2}^{ - 9} \\ = \frac{1}{ {2}^{9} } \\ = \frac{1}{512} [/tex]

[tex] \\ [/tex]

Nomor 3

[tex] {2}^{2} \times {3}^{2} \times {4}^{ - 1} \\ \\ = \not4 \times 9 \times \frac{1}{ \not4} \\ \\ = 9 \times 1 \\ \\ = 9[/tex]
