Answer 1

Answer:

Q1) like terms are the ones with same variable and degree of the variable

so in i) a² + b² - 2a² + c² + 4a

= a²-2a²+4a+b²+c²

so here the liked terms r a² and -2a² which have same variable(a) and same degree(2)

ii) 3x + 4xy - 2yz + 52zy

= 52zy - 2zy + 4xy + 3x

here we have liked terms 52zy and -2zy which have same variable (zy) and degree (1) , we can aslo write yz as zy because it's the same

Q2) the stage should be the power of 2

so 1st stage = 2^1 , 2nd = 2^2 ,5th stage = 2^5 ...

11th stage = 2^11 =2048
