A. $\frac{1}{4}$ B. $\frac{1}{2}$ C. $2$ D. $8$ E. $16$ (UTBK 2023) JAWAB: (B) $\left(\frac{16^{^{\frac{1}{4}}}}{4^{^{\frac{3}{4}}}}\right)^2=\left(\frac{\left(2^4\right)^{^{\frac{1}{4}}}}{\left(2^2\right)^{^{\frac{3}{4}}}}\right)^2$ $=\left(\frac{2^{^{\frac{4}{4}}}}{2^{^{\frac{6}{4}}}}\right)^2$ $=\left(2^{^{\frac{-2}{4}}}\right)^2$ $=2^{^{\frac{-2}{4}\times 2}}$ $=2^{^{\frac{-4}{4}}}$ $=2^{-1}$ $=\frac{1}{2}$ 2. Nilai $\left(\frac{5-\frac{1}{2}}{25-\frac{5}{2}}\right)^2=$ .... A. $\frac{1}{5}$ B. $\frac{1}{25}$ C. 0 D. $\frac{3}{5}$ E. $\frac{5}{2}$ (UTBK 2023) JAWAB: (B) $\left(\frac{5-\frac{1}{2}}{25-\frac{5}{2}}\right)^2=\left(\frac{\frac{5\times2-1}{2}}{\frac{25\times 2-5}{2}}\right)^2$ $=\left
