(b) $220\times 35000$

(c) $40÷20000$

(d) $82800÷0.12$

(e) $\frac{1.728\times 17.28}{0.0001728}$

(f) $\frac{\left(16000\right)\left(0.0002\right)\left(1.2\right)}{\left(2000\right)\left(0.006\right)\left(0.00032\right)}$

(g) $\frac{0.004\times 32000\times 0.6}{6400\times 3000\times 0.08}$

(h) $\left(\sqrt{14400}\right)\left(\sqrt{0.000025}\right)$

(i) $\sqrt[3]{2.7\times {10}^7}\sqrt[3]{1.25\times {10}^{-4}}$

(j) $\left(1\times {10}^{-3}\right){\left(2\times {10}^5\right)}^2$

(k) $\frac{{\left(3\times {10}^2\right)}^3{\left(2\times {10}^{-5}\right)}^2}{3.6\times {10}^{-8}}$

(l) $8{\left(2\times {10}^{-2}\right)}^{-3}$
