Answer 1

Ответ:

1.

$6 {}^{3} x {}^{3} = (6x) {}^{3}$

2.

$( - 2) {}^{5} x {}^{3} = - 32x {}^{3}$

3.

$- 4 \times 2 {}^{3} + 3 \times 5 {}^{2} = - 4 \times 8 + 3 \times 25 = - 32 + 75 = 43$

4.

$= - 8 - 1 + 16 - 6 = - 9 + 10 = 1$

5.

$0.3 {}^{7} \times 0.09 = 0.3 {}^{7} \times 0.3 {}^{2} = 0.3 {}^{9}$

6.

$\frac{7 {}^{3} \times 7 {}^{8} }{7 {}^{9} } = \frac{7 {}^{8 + 3} }{7 {}^{9} } = \frac{7 {}^{11} }{7 {}^{9} } = 7 {}^{11 - 9} = 7 {}^{2}$

7.

$\frac{(5 {}^{7} ) {}^{2} \times 5 {}^{9} }{5 {}^{25} } = \frac{5 {}^{14 + 9} }{5 {}^{25} } = 5 {}^{23 - 25} = 5 {}^{ - 2}$
