Question

Evaluate the expression (ab)^2for a=2 and b=5

Answer 1

Answer:
`(ab)^2=(2*5)^2=10^2=100`

Explanation:

Given the following expression:

`(ab)^2`

You know that the value of "a" is:

`a=2`

And "b" is:

`b=5`

Therefore, in order to evaluate the given expression for
`a=2` and
`b=5`, you need to substitute these values into the expression:

`(ab)^2=(2*5)^2`

Now solve the multiplication inside the parentheses:

`=10^2`

Since
`10^2=10*10`, you get:

`=100`

Answer 2

(ab)^2 = (10)^2 = 100 .....

Explanation:

The given expression is:

(ab)^2

where a = 2

b = 5

Now put the values of a and b in the expression:

(a*b)^2

(2*5)^2

Multiply 2 and 5 and then find the square of the value.

(10)^2

(10)^2 means multiply 10 two times

10*10 = 100

(10)^2 = 100 .....
