Question

Прошу помогите, очень срочно

Answer 1

1.

1)

${5}^{2}$

2)

${3}^{ - 2}$

3)

${2}^{ - 7}$

2.

1)

$10 {a}^{2} {b}^{ - 2}$

$10 {a}^{2} \times \frac{1}{ {b}^{2} }$

$\frac{10 {a}^{2} }{ {b}^{2} }$

2)

${x}^{2} {y}^{ - 4} \times 3 {x}^{ - 9} {y}^{5}$

$3 {x}^{ - 7}y$

$3 \times \frac{1}{ {x}^{7} } \times y$

$\frac{3y}{ {x}^{7} }$

3.

${34}^{ - 9}$

4.

$13.312 \times {10}^{ - 4 + 7}$

$13.312 \times {10}^{3}$

$1.3312 \times {10}^{4}$

5.

$\frac{ {a}^{ - 7} }{( { {a}^{3}) }^{ - 3} }$

$\frac{ {a}^{ - 7} }{ {a}^{ - 9} }$

${a}^{2}$
