Answer 1

Answer:

Step-by-step explanation:

Hi,

As it is your first time doing algebra I am going to try my best that you understand this question well

Here's your answer

2x^2y-5yz+xy^2

Given: x=1, y=2 and z=5

In this question all the values are given and thus, we have to substitute the values in the equation with x=1, y=2 and z=5 (that is replace all the x with 1, replace all the y with 2 and replace all the z with 5)

So we will get,

(2*1^2*2)-(5*2*5)+(1*2^2)

1^2=1          (x to the power y means multiply x y times

2^2=2        that is,2^2=2*2 and 2*3=2*2*2)

By solving the powers, we will get.............

(2*1*1*2)-(5*2*5)+(1*2*2)

4-50+4=-42

HOPE IT HELPED YOU
