Penjelasan dengan langkah-langkah:
A.
[tex] = \frac{ {4}^{3} \times {2}^{ -3 } }{ {2}^{4} } [/tex]
[tex] = \frac{ {2}^{6} \times {2}^{ - 3} }{ {2}^{4} } [/tex]
[tex] = \frac{ {2}^{6 + ( - 3)} }{ {2}^{4} } [/tex]
[tex] = {2}^{(6 + ( - 3)) - 4} [/tex]
[tex] = {2 }^{3 - 4} [/tex]
[tex] = {2}^{ - 1} = \frac{1}{2} [/tex]
[tex] \: \: [/tex]
B.
[tex] = {9}^{2} \div \frac{1}{ {3}^{3} } \times \frac{1}{ {3}^{ - 4} } [/tex]
[tex] = {3}^{4} \div {3}^{ - 3} \times {3}^{4} [/tex]
[tex] = {3}^{4 - ( - 3)} \times {3}^{4} [/tex]
[tex] = {3}^{(4 - ( - 3)) + 4} [/tex]
[tex] = {3}^{7 + 4} [/tex]
[tex] = {3}^{11} [/tex]
Penjelasan dengan langkah-langkah:
1). (4³ . 2^-3)/(2⁴) = (2²)³ . (2^-3) / 2⁴ = (2⁶ . 2^-3)/2⁴ = 2³/2⁴ = 2^(3-4)= 2^-1 = 1/2
2). 9² : 1/3³ . 1/3^-4 = 1/3^-4 : 1/3³ . 1/3^-4 = (1/3)^-4 : (1/3)³ x (1/3)^-4
= (1/3)^(-4-3-4)
= (1/3)^(-11)
= 3^11
