96. Обчисліть значення виразу:

$a)3.24 \times {10}^{2} = 3.24 \times 100 = 324$

$б)( {3}^{4} + 19) {}^{5} = (81 + 19 {)}^{5} = 10 {0}^{5} = {10}^{10}$

$в)(0.875 + 0. {5}^{3} {)}^{10} = ( \frac{7}{8} + (\frac{1}{2} ) {}^{3} ) {}^{10} = ( \frac{7}{8} + \frac{1}{8} ) {}^{10} = 1 {}^{10} = 1$

$г)( - 0.3) {}^{4} \times 10 {}^{3 } = 0.3 {}^{4} \times 10 {}^{3} = 0.3 \times 3 {}^{3} = 0.3 \times 27 = 8.1 = \frac{81}{10}$

$ґ)( \frac{2}{3} ) {}^{3} \times( \frac{3}{4} ) {}^{2} = \frac{8}{27} \times \frac{9}{16} = \frac{1}{3} \times \frac{1}{2} = \frac{1}{6} = 6 {}^{ - 1}$

$д)(4 {}^{4} - 3 {}^{5} - 13) {}^{12} = (256 - 243 - 13) {}^{12} = 0 {}^{12} = 0$
