Answer 1

Solution:

• I have attached the answer in the pic. See the pic.

Formulae Used:

$\tt \mapsto {x}^{a - b} = \dfrac{ {x}^{a} }{ {x}^{b} }$

Additional Formulae:

$\tt \mapsto {x}^{a} \times {x}^{b} = {x}^{a + b}$

$\tt \mapsto {x}^{0} = 1 \: \: \: (x \neq0)$

$\tt \mapsto ({x}^{a})^{b} = {x}^{ab}$

$\tt \mapsto {x}^{a} \times {y}^{a} = {xy}^{a}$

$\tt \mapsto \dfrac{{x}^{a}}{{y}^{a}} = { \bigg( \dfrac{x}{y} \bigg)}^{a}$

$\tt \mapsto {x}^{y} = \dfrac{1}{ {x}^{ - y} }$

$\tt \mapsto {x}^{a} = {y}^{a} \: or \: x = y \: \: (a \neq 0)$

$\tt \mapsto {a}^{x} = {a}^{y} \: or \: x = y \: \: (a \neq 1)$
