Question

por favor, ayudenme :ccc

Answer 1

Respuesta:

2)

a. 300 =4x

75 = x

b.

$\sqrt[3]{x} = 7 \\ x = {7}^{3} \\ x = 343$

c.

${x}^{2} = 64 \\ x= \sqrt{64} \\ x = 8$

d.

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

e.

$2. \sqrt{144} + 3 \sqrt[3]{343} = x.5 \\ 2.12 + 3.7 = 5x \\ 24 + 21 = 5x \\ 45 = 5x \\ 9 = x$

f.

$\sqrt{225} - \sqrt[3]{216} + 200 = 100 + {x}^{2} + 9 \\ 15 - 6 + 200 = 109 + {x}^{2} \\ 209 - 109 = {x}^{2} \\ 100 = {x}^{2} \\ 10 = x$
