Solve for: 3 b ^ /(1) 2 (b-b ^ /(1) 2)

Expression: $$3 b ^ { \frac { 1 } { 2 } } ( b - b ^ { \frac { 1 } { 2 } } )$$

Use the distributive property to multiply $3b^{\frac{1}{2}}$ by $b-b^{\frac{1}{2}}$.

$$3b^{\frac{1}{2}}b-3b$$

To multiply powers of the same base, add their exponents. Add $\frac{1}{2}$ and $1$ to get $\frac{3}{2}$.

$$3b^{\frac{3}{2}}-3b$$
