Answer:
1. 3/x • 2/x²
3x2/x•x²
6/x•x²
6/ x¹• x²
6/x¹+²
=6/x³
2. 3m/12n³ • 8n/6m²
m/4n³ • 8n/6m
1/4n² • 8/6m
1/4n² • 4/3m
1/n² • 1/3m
= 1/3mn²
3. 2x/5 • 3/4x
2x1/5 • 3/4
1/5 • 3/2
= 3/10
4. 3/x ÷ 4/x
3/x × x/4
3×1/4
= 3/4
5. 4g²/6h² + 8g/12gh
2g²/3h²+8g/12gh
2g²/3h² + 8/12h
2g²/3h² + 2/3h
= 2g²+2h/3h²
Hope it'll helps!;)
