body, td, input { font-family:arial; font-size:16px; } #container { padding:5px 20px; } #header h2 { font-size:27px; color:#d0d0d0; margin: 22px 0 10px; } #searchform { width:470px; margin:0; } #searchform input { font-size:18px; border: 1px solid #aaa; color:#aaa; } #searchform input:hover, #searchform input:focus, #searchform input:active { border: 1px solid #888; color:#000; } #searchform input.searchbox { padding:4px; width:300px; } #searchform input.searchbutton { padding: 3px 10px; color:#000; } #searchform div.poweredby { float:right; width:80px; text-align:center; } #searchform div.poweredby span { font-size:10px; } #searchform div.poweredby img { width:60px; } First of all, that 2^x can be divided on both sides resulting x^2=1. sqroot both sides then 1^(1/2)=1 *Please ignore the Bing commercial

multiply x^2 by each term inside the parentheses. The bases are the same,then two expressions are only equal if the exponents arealso equal. x=x Since x contains the variable to solvefor, move it to the left-hand by subtracting x from both sides. x-x=0 alway true
