Question

Choose the correct simplification of the expression (2x2y6z5)(5x4y5z3).

10x8y30z15
7x6y11z8
7x8y30z15
10x6y11z8

Answer 1

Option D) 10x6y11z8

Explanation:

Answer 2

The correct option is 4.

Explanation:

The given expression is

`(2x^2y^6z^5)(5x^4y^5z^3)`

Simplify the given expression.

`(2x^2y^6z^5)* (5x^4y^5z^3)`

`(2* 5)(x^2x^4)(y^6y^5)(z^5z^3)`

`10x^(2+4)y^(6+5)z^(5+3)`
`[\because x^mx^n=x^(m+n)]`

`10x^6y^(11)z^8`

Therefore correct option is 4.
