Jawablah bagian 1b-1e !!

1b. 2 $2^{5} . 3^{6} . 4^{6} = 2^{5} . 3^{6} . 2^{12} = 2 ^{5+12} . 3^{6} = 2^{17} . 3^{6}$
1c. $frac{ 2^{5}. 3^{5}. 4^{2} }{ 12^{2} } = frac{ 2^{5}. 3^{5}.2^{4} }{ 3^{2}. 2^{4} }= frac{ 2^{9}. 3^{5} }{2^{4}.3^{2}}= 2^{5} . 3^{3}$
1d. $frac{ (-5)^{6}. 25^{2} }{125} = frac{(-5)^{6}. 5^{10} }{ 5^{3} } = (-5)^{6}.5^{7}$
1e. $frac{ 3^{7}. 7^{3}.2 }{ 42^{3} } = frac{3^{7}. 7^{3}. 2^{1} }{ 2^{3}. 3^{3}. 7^{3} } = frac{ 3^{4} }{ 2^{2} }$
