Nilai x yg memenuhi adalah………………….

${a}^{b} times {a}^{c} = {a}^{b + c}$
$frac{ {3}^{x + 1} + {3}^{x + 2} + {3}^{x + 3} }{39} = 27 \ frac{3 times {3}^{x} + {3}^{2} times {3}^{x} + {3}^{3} times {3}^{x} }{39} = 27 \ frac{3 times {3}^{x} + 9 times {3}^{x} + 27 times {3}^{x} }{ 39 } = 27 \ frac{3p + 9p + 27p}{39} = 27 \ frac{39p}{39} = 27 \ p = 27 \ {3}^{x} = {3}^{3} \ x = 3$
jika p dimisalkan 3^x
maka X adalah 3

semoga membantu…
