Answer 1

Respuesta:

holi :3

Explicación paso a paso:

a)

${x}^{2} = 36 \\ x = \sqrt{36} \\ x = 6$

b)

$\sqrt{x} = 2 \\ x = {2}^{2} \\ x = 4$

c)

${x}^{3} = 8 \\ x = \sqrt[3]{8} \\ x = 2$

d)

$\sqrt[3]{x} = 2 \\ x = {2}^{3} \\ x = 8$

e)

${x}^{4} = 81 \\ x = \sqrt[4]{81} \\ x = 3$

Ejercicios

1)

${x}^{2} - 1 = 8 \\ {x}^{2} = 9 \\ x = \sqrt{9} \\ x = 3$

2)

$\frac{ {x}^{4} }{8} + 1 = 33 \\ {x}^{4} + 8 = 264 \\ {x}^{4} = 256 \\ x = \sqrt[4]{256} \\ x = 4$

3)

$2 {x}^{3} + 1 = 55 \\ 2 {x}^{3} = 54 \\ {x}^{3} = 27 \\ x = \sqrt[3]{27} \\ x = 3$

4)

$(x + 1) ^{3} = 64 \\ \sqrt[3]{(x + 1)^{3} } = \sqrt[3]{64} \\ (x + 1) = 4 \\ x = 3$

5)

$\sqrt{x} - 3 = 4 \\ \sqrt{x} = 7 \\ x = {7}^{2} \\ x = 49$

6)

${3} \times { \sqrt[4]{x} } = 6 \\ \sqrt[4]{x} = 2 \\ x = {2}^{4} \\ x = 16$

7)

$\sqrt{x + 2} = 3 \\ ( \sqrt{x + 2} )^{2} = {3}^{2} \\ x + 2 = 9 \\ x = 7$

8)

$\sqrt[3]{x - 4} - 1 = 4 \\ \sqrt[3]{x - 4} = 5 \\ ( \sqrt[3]{x - 4} )^{3} = {5}^{3} \\ x - 4 = 125 \\ x = 129$
