Solve logarithm by hand
WebTo solve for x x, we must first isolate the exponential part. To do this, divide both sides by 5 5 as shown below. We do not multiply the 5 5 and the 2 2 as this goes against the order of operations! \begin {aligned} 5\cdot 2^x&=240 \\\\ 2^x&=48 \end {aligned} 5 ⋅ 2x 2x = 240 = 48. Now, we can solve for x x by converting the equation to ... WebIf this cannot be done, more traditional methods of solving must be used. To solve any equation, inverses of the operations are used to get the variable alone. To undo multiplication, divide; to undo squaring, square root; to undo exponential, logarithm. So to solve an exponential equation use the inverse, a logarithm.
