(ii) 1256.249

Ans : Missing

Q.3: Simplify and write in exponential form. 
(i) (–2)–3 × (–2)– 4 
(ii) p3 × p–10 
(iii) 32 × 3–5 × 36

Ans : Missing

Q.4: Evaluate
\(\begin{array}{lll}{\text { (i) } 3^{-2}} & {\text { (ii) }(-4)^{-2}} & {\text { (iii) }\left(\frac{1}{2}\right)^{-5}}\end{array}\)

Ans : (i) \(3^{3^{-2}}=\frac{1}{3^{2}}=\frac{1}{9}\quad\left(a^{-m}=\frac{1}{a^{m}}\right)\) (ii) \((-4)^{(-4)^{-2}}=\frac{1}{(-4)^{2}}=\frac{1}{16}\quad\left(a^{-m}=\frac{1}{a^{m}}\right)\) (iii) \(\left(\frac{1}{2}\right)^{-5}=\frac{1}{(2)^{-5}}=(2)^{5}=2 \times 2 \times 2 \times 2 \times 2=32\)

Q.5: Simplify and express the result in power notation with positive exponent.
\(\begin{array}{l}{\text { (i) }(-4)^{5} \div(-4)^{8} \quad \text { (ii) }\left(\frac{1}{2^{3}}\right)^{2}} \\ {\text { (ii) } \quad(-3)^{4} \times\left(\frac{5}{3}\right)^{4} \text { (iv) }\left(3^{-7} \div 3^{-10}\right) \times 3^{-5}\left(\text { v) } 2^{-3} \times(-7)^{-3}\right.}\end{array}\)

Ans : \(\begin{array}{l}{\quad(i)(-4)^{5} \div(-4)^{8}=(-4)^{5-8}\left(a^{m} \div a^{n}=a^{m-n}\right)} \\ {=(-4)^{-3}}\end{array}\) \(=\frac{1}{(-4)^{3}} \quad \quad \quad \quad\left(a^{-m}=\frac{1}{a^{m}}\right)\) (ii) \(\left(\frac{1}{2^{3}}\right)^{2}=\frac{1}{\left(2^{3}\right)^{2}}=\frac{1}{2^{6}}\) \(\left(\left(a^{m}\right)^{n}=a^{a n}\right)\) (iii) \((-3)^{4} \times\left(\frac{5}{3}\right)^{4}=(-1 \times 3)^{4} \times \frac{5^{4}}{3^{4}}\) \(=(-1)^{4} \times 3^{4} \times \frac{5^{4}}{3^{4}} \quad\left[(a b)^{m}=a^{m} \times b^{m}\right]\) \(\begin{array}{l}{=(-1)^{4} \times 5^{4}} \\ {=5^{4}}\end{array}\left[(-1)^{4}=1\right]\) \(\begin{array}{l}{(\mathrm{iv})\left(3^{-7} \div 3^{-10}\right) \times 3^{-5}=\left(3^{-7-(-10)}\right) \times 3^{-5}\left(\mathrm{a}^{m} \div \mathrm{a}^{n}=a^{m-n}\right)} \\ {=3^{3} \times 3^{-5}} \\ {=3^{3+(-5)}\left(\mathrm{a}^{m} \times \mathrm{a}^{n}=\mathrm{a}^{m+n}\right)} \\ {=3^{-2}}\end{array}\) \(=\frac{1}{3^{2}}\) \(\left(a^{-m}=\frac{1}{a^{m}}\right)\) \(\begin{array}{l}{(v) 2^{-3} \times(-7)^{-3}=^{\frac{1}{2^{3}} \times \frac{1}{(-7)^{3}}}} \\ {=\frac{1}{[2 \times(-7)]^{3}}} \\ {=\frac{1}{(-14)^{3}}}\end{array}\) Hint : \(\left(a^{-m}=\frac{1}{a^{m}}\right)\) Hint : \(\left[a^{m} \times b^{m}=(a b)^{m}\right]\)
