amm1812

See, pls, the suggested explanation:
3(5x-1)²=27 ⇔ 75x²-30x-24=0 ⇔ 25x²-10x-8=0 ⇒
$\left[\begin{array}{ccc}x= \frac{5-15}{25} \\x= \frac{5+15}{25} \end{array}\right \ =\ \textgreater \ \ \left[\begin{array}{ccc}x=- \frac{2}{5} \\\ x= \frac{4}{5} \end{array}\right$

Evaluate each of the following to three significant figures, and express each answer in SI units using an appropriate prefix: (a

Softa [21]

Answer:

a). $4.86\times 10^{-15}$ m

b). $4.21\times 10^{-2}$ m³

c). $7.00\times 10^{3}$ N²

Step-by-step explanation:

In this question we have to convert each option into SI units.

a). $4.86(10^{-6})^{2}$ mm

= $4.86\times (10^{-12})\times (10^{-3} )$ m

= $4.86\times 10^{-15}$ m

b). (348 mm)³

= $(348)^{3}\times (10^{-3})^{3}$ m³

= $42144192\times 10^{-9}$ m³

= $4.21\times 10^{-2}$ m³

c). $(83700)^{2}\times (10^{-3})^{2}$ N²

= $700569\times 10^{4}\times 10^{-6}$ N²

= $7.00\times 10^{9}\times 10^{-6}N^{2}$

= $7.00\times 10^{3}$ N²
