Question

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

Answer 1

Answer:

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

Step-by-step 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 .....

Answer 2

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

Step-by-step 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:

$=100$
