Product= -2/3a²b × 6/5a³b²,

= -2a²b × 2/5a³b²,


=-4/5 . a^5 . b^3,


Checking:-

put a=2, b=3


(-2/3 × 2² × 3) × (6/5 × 2³ × 3²),

(-2×2²) × ( 6/5 × 8 × 9),


-8 × 432/5,

3456/5,


now

-4/5 × 2^5 × 3^3,

-4/5 × 32 × 27,

-3456/5

Here is your solution

 = - \frac{2}{3} a {}^{2} \times \frac{6}{5} a {}^{3} b {}^{2} \\ \\ = - \frac{2}{3} (2) {}^{2} \times \frac{6}{5} (2) {}^{3} (3) {}^{2} \\ \\ = - \frac{ 2}{3} \times 4 \times \frac{6}{5} \times 8 \times 9 \\ \\ = - \frac{8}{\cancel3} \times \frac{24}{5} \times \cancel(72) {}^ \: {24} \\ = - 192 \times 24 \\ = <strong>-4608</strong>

I hope it helps you
