Please repeat 4 again I can't see clearly

4) $(14.2)^4 \times (14.2)^{1/4}$ Step 1: Apply the exponent rule for multiplication, which states that when multiplying powers with the same base, you add the exponents: $a^m \times a^n = a^{m+n}$. $(14.2)^4 \times (14.2)^{1/4} = (14.2)^{4 + \frac{1}{4}}$ Step 2: Add the exponents. To do this, find a common denominator for 4 and $\frac{1}{4}$. $4 + \frac{1}{4} = \frac{16}{4} + \frac{1}{4} = \frac{16+1}{4} = \frac{17}{4}$ Step 3: Substitute the sum of the exponents back into the expression. $(14.2)^{\frac{17}{4}}$ Final answer: $\boxed{(14.2)^{\frac{17}{4}}}$
