Question

x² = 64² + 32² aflati x​

Answer 1

Răspuns:

$x^2=64^2+32^2\\x^2=(2^6)^2+(2^5)^2\\x^2=2^1^2+2^1^0\\x^2=2^1^0(2^2+1)\\x^2=1024(4+1)\\x^2=1024*5\\x^2=5120\\x1=+\sqrt{5120}=+32\sqrt{5} \\x2=-\sqrt{5120}=-32\sqrt{5}$

Answer 2

Explicație pas cu pas:

$\large \bf \: {x}^{2} = 64^{2} + 32^{2}$

$\large \bf \: {x}^{2} = 4096 + 1024$

$\large \bf \: {x}^{2} = 4096 + 1024$

$\large \bf \: {x}^{2} = 5120$

$\large \bf x =\pm \sqrt{5120}$

$\large \bf x_{1} = - 32\sqrt{5} \: \: si \: \: x_{2} = + 32\sqrt{5}$
