Question

7) Efetue as potenciações.
a) (2√3)²=
b) (3√5)²=
c) (√2)⁶=
d) (2³√5)³=
e) (-7√2)²=


​

Answer 1

$a)(2 \sqrt{3} ) ^{2} = 4 \sqrt{9} = 4 \times 3 = 12 \\ \\ b)(2 \sqrt{5} ) ^{2} = 4 \sqrt{25} = 4 \times 5 = 20 \\ \\ c) (\sqrt{2} ) ^{6} = \sqrt{64} = 8 \\ \\ d)( {2}^{3} \sqrt{5} ) ^{3} = 8 \sqrt{125} = 512 \times 5 \sqrt{5} = 2560 \sqrt{5} \\ \\ e)( - 7 \sqrt{2} ) ^{2} = 49 \sqrt{4} = 49 \times 2 = 98$
