Question

Express each of the following as a rational number of the form , where p and q are integers and q 0: (i) 2 -3 (ii) (-4) -2 (iii) (iv) (v)

Philoid · Accepted Answer

(i) 2^-3 = = [Using a^-n = ]

(ii) (-4)^-2 = = = [Using a^-n = ]

(iii) = [Using ⁿ]

(iv) = = = [Using ^-n = ]

(v) = = [Using ^-n = ]
