Simplify b^(1/3)*b^(4/3)

$b^{\frac{1}{3}} \cdot b^{\frac{4}{3}}$

Step 1

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$b^{\frac{1}{3} + \frac{4}{3}}$

Step 2

Combine the numerators over the common denominator.

$b^{\frac{1 + 4}{3}}$

Step 3

Add $1$ and $4$ .

$b^{\frac{5}{3}}$
