Ok first of all, I EXTREMELY appreciate your use of parenthesis. Ok so first just raise both sides to the power of 1/2.

(\frac{3}{8})^{x}=\frac{8}{11}

You'll see why I didn't include a negative. Then apply the log base 3/8 and you get

x =   log_{ \frac{3}{8} }( \frac{8}{11} )
Then you split the log up and you get
x =  log_{ \frac{3}{8} }(8)  -  log_{ \frac{3}{8} }(11)
You couldn't put a negative value for a log. That is why I excluded the negative part of the sqrt.

<span>Simplifying x + -1.4 = 7.82 Reorder the terms: -1.4 + x = 7.82 Solving -1.4 + x = 7.82 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.4' to each side of the equation. -1.4 + 1.4 + x = 7.82 + 1.4 Combine like terms: -1.4 + 1.4 = 0.0 0.0 + x = 7.82 + 1.4 x = 7.82 + 1.4 Combine like terms: 7.82 + 1.4 = 9.22 x = 9.22 Simplifying x = 9.22</span>
