WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The problem is that the numerator and denominator are the wrong way around. So raise both sides to the power of -1. That gives (5/2)-2=4/25, so x=-2. WebSolve. 15*+2 = 4(7*-1) for x using logarithms.
