Question

give me answer of this

Answer 1

⇒3^(x+2) -9 =9*8

⇒3^(x+2) = 81

⇒(x+2) = 4

⇒x=2

Answer 2

Heya ! Here ia u r Ans >
_________________________________________
$(3 {}^{x + 2} - 9) \div 8 = 9$

$= \frac{3 {}^{x + 2} - 9}{8}$

$= 3 {}^{x + 2} - 9 = 72$

$= 3 {}^{x + 2} = 72 + 9$

$= 3 {}^{x + 2} = 81$

$= 3 {}^{x + 2} = 3 {}^{4}$
$x + 2 = 4$

$x = 4 - 2$
$x = 2$
