Question

$x^{2} = 2 ^{26} + 2^{29} + 2^{30} \\ x = ?$
​

Answer 1

$x^{2} = 2^{26} + 2^{29} + 2^{30} \\ x^{2} = (1 + 2^{3} + 2^{4}) \times 2^{26} \\ x^{2} =(1 + 8 + 2^{4}) \times 2^{26} \\x^{2} =(1 + 8 + 16) \times 2^{26} \\ x ^{2} = 25 \times 2 ^{26} \\ x = + - \sqrt{40960} \\ x = - 40960 \\ x = 40960$
