help in exponents
plz ​

Answer 1

Answer:

x = –8

For solution , please refer to the attachment .

Note:

★ a^m × a^n = a^(m + n)

★ a^m / a^n = a^(m – n)

★ a^m × b^m = (a×b)^m

★ a^m / b^m = (a/b)^m

★ [ a^m ]^n = a^mn

★ a^(-n) = (1/a)^n

★ (a/b)^(-n) = (b/a)^n

★ a^m = a^n => m = n

Answer 2

Answer:

x = (-8)

Step-by-step explanation:

[(2/3)^⅓]^{x-1} = 27/8

=> [(2/3)^⅓]^{x-1} = (3/2)³

=> [(2/3)^⅓]^{x-1} = (2/3)^{-3}

=> {x-1}/3 = -3

=> x-1 = -9

=> x = -9+1

=> x = (-8)
