Answer 1

$\huge\underbrace\mathbb\pink{Answer}$

$\star0.000000564 = 5.64 \times {10}^{ - 7} </p><p></p><p>$

$\star0.0000021 = 2.1 \times {10}^{ - 6}$

$\star21600000 = 2.16 \times {10}^{ 7}$

$\star0.000000000 = 9.42 \times {10}^{ - 10}$

2. a)

$\frac{352}{100} \times {10}^{5}$

$352 \times \frac{ {10}^{5} }{ {10}^{2} }$

$using \: \frac{ {a}^{m} }{a {}^{n }} = {9}^{m - n}$

$352 \times 10 {}^{5 - 2}$

$352 \times {10}^{3}$

$\red\longrightarrow352000$

b)

$\star0.000754$

c)

$\star0.000000325$

d)
