Answer 1

Answer:

jaab same number hai toh same hi likhe ga naa

because there is writen is equal so ve mark equal simple

hope you understand

Don't mark brainliest

Answer 2

Step-by-step explanation:

you take 239^2 common.

239^2(1+239)

so it becomes 239^2 x 240

that's why it's d option. If you can't understand from this lets make 239 a variable x

Then, by the question,

a^2 + a^3

Taking a^2 common we get,

a^2(1+a) [you will see that dividing a^3 by a^2 gives a because two a denominator will cut 2 from numerator leaving single a, hence in bracker it will be 1+a]

Now again if you put value, then being the rule of bracket you have to solve brackets first.

That will be ultimately d option if u put value of a and solve bracket similar to how I explained at beginning.
