To solve the equation \( 1-4(3x-3)^{\frac{3}{2}}=-107 \), let's first isolate the term with the variable. Begin by moving \( 1 \) to the other side: \[ -4(3x-3)^{\frac{3}{2}} = -108 \] Next, divide by \(-4\): \[ (3x-3)^{\frac{3}{2}} = 27 \] Now, take both sides to the power of \(\frac{2}{3}\) to eliminate the exponent: \[ 3x-3 = 27^{\frac{2}{3}} \] Calculating \( 27^{\frac{2}{3}} \): \[ 27 = 3^3 \implies 27^{\frac{2}{3}} = (3^3)^{\frac{2}{3}} = 3^2 = 9 \] So now we have: \[ 3x-3 = 9 \] Add \(3\) to both sides: \[ 3x = 12 \] Finally, divide by \(3\): \[ x = 4 \] Thus, the solution to the equation is \( x = 4 \).
