b) \( \sqrt[2]{125 / 64}-(4 / 15: 8 / 5+1 / 3)^{2}= \) c) \( \sqrt{49 / 121}+(2 / 3: 1 / 9)^{2}= \) d) \( \sqrt[2]{8 / 125}+(1 / 2+1-2 / 3)= \) e) \( (3 / 5)^{2}: 12 / 25+\sqrt{7 / 3-5 / 9}= \)

\( 30 \times\left(\frac{1}{2}\right. \) of 70\( )= \)

Calculate: \( \frac{100}{25}+2 \backslash \operatorname{sqrt}(49) \) A 14 B 16 C 18 D 20

SECTION-E \( [4 \times 3=12] \) 18. (i) Express \( \left(1.6 \times 10^{9}\right) \times\left(5.0 \times 10^{-3}\right) \) in the form of \( \mathrm{k} \times 10^{\mathrm{n}} \). (ii) Evaluate : \( \left[4^{2}-3^{2}\right]+\left(\frac{1}{7}\right)^{2} \)

An example of the identity property of zero is:
