And (14.2)¼ = 3.55?

No, $(14.2)^{1/4}$ is not equal to 3.55.

Step 1: Calculate $(14.2)^{1/4}$. This means finding the fourth root of 14.2. $(14.2)^{1/4} \approx 1.9410$ Your value of 3.55 is obtained by dividing 14.2 by 4 ($14.2 \div 4 = 3.55$), which is not the correct way to calculate a fractional exponent.

Final answer: $\boxed{(14.2)^{1/4} \approx 1.9410}$
