Answer:

x = 3.5

Step-by-step explanation

Using the rules of exponents


a^(m) ×
a^(n)
a^((m+n)) and
√(a) =
a^{(1)/(2) }

Then

36
√(6) = 6² ×
6^{(1)/(2) } =
6^((2+0.5)) =
6^(2.5)

Thus


6^(x-1) =
6^(2.5)

Since the bases on both sides are equal, both 6, equate the exponents

x - 1 = 2.5 ( add 1 to both sides )

x = 3.5

Answer:


x = (7)/(2)

Explanation:


6^(x-1) = 36 \sqrt6\\\\6^(x-1) = 6^2 * 6^{(1)/(2)}\\\\6^(x-1) = 6^{2 + (1)/(2) }
[ \ a^x * a^ y = a^(x+ y) \ ]


x - 1 = 2 + (1)/(2)
[ \ b^x = b^y => x = y \ ]


x = 2 + (1)/(2) + 1\\\\x = 3 + (1)/(2) \\\\x = (6+ 1)/(2) \\\\x = (7)/(2)
