1)
(3х)ⁿ = 729х⁶
(3х)ⁿ = 3⁶х⁶
(3х)ⁿ = (3х)⁶
n = 6

2)
(0,3a³)ⁿ * 1000 = 27a⁹
(0,3a³)ⁿ = 27a⁹ : 1000
(0,3a³)ⁿ = 0,027a⁹
(0,3a³)ⁿ = 0,3³(a³)³
(0,3a³)ⁿ = (0,3a³)³
n = 3

3)
(-1/2 a³b)ⁿ = - 1/32 a¹⁵b⁵
(-1/2 a³b)ⁿ = (-1/2)⁵ (a³)⁵b⁵
(-1/2 a³b)ⁿ = (-1/2 a³b)⁵
n = 5

4)
$(3 \frac{1}{3} x^{6} )^{n}*0,0001= \frac{1}{81} x^{24}$
$( \frac{10}{3} x^{6} )^{n}= \frac{1}{81} x^{24}:0,0001$
$( \frac{10}{3} x^{6} )^{n}= \frac{1000}{81} x^{24}$
$( \frac{10}{3} x^{6} )^{n} = ( \frac{10}{3} )^{4} ( x^{6} )^{4}$
$( \frac{10}{3} x^{6} )^{n}= ( \frac{10}{3} x^{6} )^{4}$
n = 4
