Answer is ⤵️

Option (1) 15

I hope it is helpful

Step-by-step explanation:

$\rm {(4)}^{a + 5} {(16)}^{2a} {(32)}^{4} = {(16)}^{3a}$

$\rm {(2}^{2} )^{a + 5} { {(2}^{4} )}^{2a} { {(2}^{5}) }^{4} = { {(2}^{4} )}^{3a}$

$\rm {(2)}^{2(a + 5)} {(2)}^{4(2a)} {(2)}^{5(4)} = {2}^{4(3a)}$

$\rm {(2)}^{2a + 10} {(2)}^{8a} {(2)}^{20} = {(2)}^{12a}$

$\rm{ {(2)}^{2a + 10 + 8a + 20} = {(2)}^{12a} }$

$\rm{ {(2)}^{10a +30 } = {(2)}^{12a} }$

Comparing the powers,

$\rm10a + 30 = 12a$

$\rm30 = 12a - 10a$

$\rm30 = 2a$

$\rm \frac{30}{2} = a$

$\rm15 = a$

$\rm \: or \: \: \: a = 15$
