3 \times {( \frac{1}{8} )}^{2x}  = 12 \\ \Leftrightarrow {( \frac{1}{8} )}^{2x}  = 4 \\ \Leftrightarrow  {( {2}^{ - 3}) }^{2x}  =  {2}^{2}  \\ \Leftrightarrow  {2}^{ - 6x}  =  {2}^{2}  \\ \Leftrightarrow  - 6x = 2 \\ \Leftrightarrow x =  -  \frac{1}{3}  \\  \\ 2 {\sqrt[3]{5}}^{4x}  = 50 \\ \Leftrightarrow  { \sqrt[3]{5} }^{4x}  = 25 \\ \Leftrightarrow  {5}^{ \frac{4x}{3} }  =  {5}^{2}  \\ \Leftrightarrow  \frac{4x}{3}  = 2 \\ \Leftrightarrow 4x = 6 \\ \Leftrightarrow x =  \frac{3}{2}

Find sinx given cos2x=5/9
Diano4ka-milaya [45]

Answer:

sinx = √2/3

Step-by-step explanation:

cos2x = 1-2sin²x

5/9 = 1-2sin²x

2sin²x =1-5/9

2sin²x = 4/9

sin²x = (4/9)/2

sin²x = (4/9)*(1/2)

sin²x = 2/9

sinx = √2/3
