If (x) = a^x , then (p) ^3 is equal to - Vidyadip

MCQ

If $\phi (x) = {a^x}$, then ${\{ \phi (p)\} ^3} $ is equal to

✓
$\phi (3p)$
B
$3\phi (p)$
C
$6\phi (p)$
D
$2\phi (p)$

✓

Answer

Correct option: A.

$\phi (3p)$

a
(a) $\phi \,(x) = {a^x}\, \Rightarrow \,\,\phi \,\,(p) = {a^p}$

$\therefore \,\,\,{[\phi \,(p)]^3} = {[{a^p}]^3} = {a^{3p}} = \phi \,(3p)$
