Question

вычислите: ('5)×(-5)×(-5)×(-5); (-3)×(-3)×(-3)×(-3)×(-3)×(-3); (-5/6)×(-5/6)×(-5/6)×(-5/6); (-1,3)×(-1,3)×(-1,3); 2,4×2,4×2,4; 1 1/2×1 1/2÷1 1/2×1 1/2×1 1/2:

Answer 1

1)
$( - 5) \times ( - 5) \times ( - 5) \times ( - 5) = 5 {}^{4} = 625$
или

$5 \times ( - 5) \times ( - 5) \times ( - 5) = (-5) {}^{4} = - 625$
2)
$( - 3) \times ( - 3) \times ( - 3) \times ( - 3) \times ( - 3) \times ( - 3) = 3 {}^{6} =729$
3)
$( - \frac{5}{6} ) \times ( - \frac{5}{6} ) \times ( - \frac{5}{6} ) \times ( - \frac{5}{6} ) = ( \frac{5}{6} ) {}^{4} = \frac{625}{1296}$
4)
$( - 1.3) \times ( - 1.3) \times ( - 1.3) = ( - 1.3) {}^{3} = - 2.197$
5)
$2.4 \times 2.4 \times 2.4 = 2.4 {}^{3} = 13.824$
6)
$1.5 \times 1.5 \div 1.5 \times 1.5 \times 1.5 = 3.375$
или

$1.5 \times 1.5 \times 1.5 \times 1.5 \times 1.5 = 1.5 {}^{5} = 7.59375$
