Express 0.003597 to three significant figures

coldgirl [10]

Answer:

0.00360.

Step-by-step explanation:

Leading zeros in a number are not significant, so your number has four significant figures.

You must drop the 7 from 0.003597.

Since 7 is greater than 5, you must add 1 to the 9

$\begin{array}{r|l}1& \\0.00359 &\text{7}\!\!\!\!\diagup \\\mathbf{0.00360} & \\\end{array}$

Answer:

C

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$

Note that 8 = 2³, thus

$\frac{2^{5} }{8}$

= $\frac{2^{5} }{2^{3} }$

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

= 2²
