Evaluate the following pic

1)

2)  

3) Evaluating we get

4)

5)

Step-by-step explanation:

1)

Prime factors of 1225 : 5x5x7x7

Prime factors of 1024: 2x2x2x2x2x2x2x2x2x2

2)

We know that

Applying radical rule:

So,

3)

It can be written as:

Evaluating we get

4)

Put value of x, y and z in equation and solve:

So,

5)

We know (-a)^n = (a)^n when n is even and (-a)^n = (-a)^n when n is odd

So,

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
