Tentukan nilai x yang memenuhi persamaan:

$left[( sqrt{1} + sqrt{x + 4} + 4). frac{1}{3} right] : frac{1}{5} = 10$

Good Luck ^_^

Dengan demikian:

$$begin{align}left[left(sqrt1+sqrt{x+4}+4right)timesfrac13right]:frac15&=10 \ left(sqrt1+sqrt{x+4}+4right)timesfrac13&=10timesfrac15&&text{(Ubah notasi)} \ left(sqrt1+sqrt{x+4}+4right)timesfrac13&=2 \ sqrt1+sqrt{x+4}+4&=2times3&&text{(Kalikan silang)} \ sqrt1+sqrt{x+4}+4&=6 \ 1+sqrt{x+4}+4&=6 \ sqrt{x+4}+5&=6 \ sqrt{x+4}&=6-5&&text{(Pindah ruas)}\sqrt{x+4}&=1 \ x+4&=1^2&&text{(Kuadratkan kedua ruas)} \ x+4&=1 \ x&=1-4&&text{(Pindah ruas)} \ x&=-3 end{align}$

$[( 1 + sqrt{x + 4} + 4) . frac{1}{3} ] = 10 $:$ 5 \ (1 + sqrt{x + 4} + 4) . frac{1}{3} = 2 \ (5 + sqrt{x + 4} ) = 2 $x$ 3 \ 5 + sqrt{x + 4} = 6 \ sqrt{x + 4} = 6 - 5 \ sqrt{x + 4} = 1 \ ( sqrt{x + 4} )^{2} = 1^{2} \ x + 4 = 1 \ boxed{x = 1 - 4 = -3}$
