Question

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

Answer 1

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.

Answer 2

Answer:

$10y^7$

Step-by-step explanation:

$2y^4\times 5y^3$

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

$2y^7\times 5$

Multiply 2 × 5=10

$10y^7$

Hope this helps! :)
