Answer:
20y^7. this is because the exponents are added together because the variable attached to the coefficient are the same therefor the coefficients are multiplied, and the exponents are added together.
[tex]10y^7[/tex]
Step-by-step explanation:
[tex]2y^4\times 5y^3[/tex]
In order to multiply powers of the same base, add their exponents, add 4+3=7,
[tex]2y^7\times 5[/tex]
Multiply 2 × 5=10
Hope this helps! :)
