Question

$\sqrt{ {2}^{6} \times ( {7}^{2} - {2}^{4} \times 3) = }$
Calculati va rog ( Nu vreau sa calculati fiecare putere , ci sa faceti cum trebuie ,adica nu băbește :)))) )​

Answer 1

√2⁶×(7² - 2⁴×3) =

= √2⁶×(49 - 16×3)

= √2⁶×(49 - 48)

= √2⁶×1

= √2⁶

= 2³

= 8

Answer 2

$\sqrt{2^6\cdot(7^2-2^4\cdot 3)} =\\ \\ =\sqrt{2^6\cdot (49-16\cdot 3)} =\\ \\ =\sqrt{2^6\cdot(49-48)} = \\ \\ =\sqrt{(2^3)^2\cdot 1} =\\ \\ = 2^3 =\\ \\ =8$
