Question

Evaluate (ab) 2 for a = 4 and b= 3.

A. 81
B. 144
C. 24
D. 36
i think its b

Answer 1

is the 2 supposed to be an exponent?

Answer 2

Okay so if we have (ab)2 and a=4 and b=3 then we need to replace a and b with there values.

Now before we do that we are going to set up our equation. Whenever you have things like "Ab" or "5x" you multiply them. So "A*B

In this case
(a*b)2

and since it doesn't say weather to add or subtract or anything like that, we multiply *2

So, (4*3)*2

4*3=12
12*2=24


Final answer: 24.

Answer 3

^That is if the 2 were not to be a exponent and rather just a value.

Answer 4

And if the 2 is a exponent we do the same thing, but this time you solve as you would with a exponent. So we have:

\[(4*3)^{2}\]


And so we do 4*3

4*3=12

Now we have

\[12^{2}\]


And to solve we just do

12*12

12*12=144


If you didn't know if it was a exponent, if it is it will be a small to in the top right of the equation.

@Vocaloid is this correct?
