$(( {4}^{ - 2} {)}^{2} + {4}^{ \frac{1}{2} } \times {4}^{ -3 } ) \div {4}^{ - 5} = \\ \\ ( {4}^{ - 4} + ( {2}^{2} {)}^{ \frac{1}{2} } \times {2}^{ - 6} ) \times {4}^{5} = \\ \\ ( {2}^{ - 8} + 2 \times {2}^{ - 6} ) \times {2}^{10} \\ \\ ( \frac{1}{ {2}^{8} } + {2}^{ - 5} ) \times {2}^{10} \\ \\ ( \frac{1}{ {2}^{8} } + \frac{1}{32} ) \times {2}^{10} \\ \\ \frac{32 + {2}^{8} }{32 \times {2}^{8} } \times {2}^{10} \\ \\ \frac{32 + 256}{32} \times {2}^{2} \\ \\ \frac{288}{32} \times 4 = \\ \\ 9 \times 4 = 36. \\ \\ \\ \huge\boxed{ \tt\frac{BURNS}{answers}}$
