Answer:
6x^5y^7
Step-by-step explanation:
add the exponents value together
constants - 4+2=6
x - 2+3=5
y - 3+4=7
[tex]4 {x}^{2} {y}^{3} \times 2 {x}^{3} {y}^{4} \\ 4 \times 2 \times {x}^{2} \times {x}^{3} \times {y}^{3} \times {y}^{4} \\ 8 \times {x}^{2 + 3} \times {y}^{3 + 4} \\ = 8 {x}^{5} {y}^{7} [/tex]
