Question

2y^4 x 5y^3 please can you help me

Answer 1

`10y^7`

Explanation:

`2y^4* 5y^3`

In order to multiply powers of the same base, add their exponents, add 4+3=7,

`2y^7* 5`

Multiply 2 × 5=10

`10y^7`

Hope this helps! :)

Answer 2

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.
