Question

give a counter example to show that each statement is false, the domain of each variable is the set of real numbers..... number 1 said
1. if a2=b2, then a=b
idk how yo do it??

Answer 1

Let a = 2 and b = 3

Since they are different numbers, the statement a = b is already false because 2 cannot equal 3. Same thing with a^2 = b^2 because a and b are different numbers.

Answer 2

what is
1.59x+4.23=3.56x+2.12
