Question

A={-7,5,2} and B= {3√125,√4,√49} are the sets A and B equal?
justify your answer

Answer 1

NO, because root of 125 is 25 and root of 4 is 2 and root of 49 is 7. SO, THE equation will be {3,25,2,7}.

Answer 2

Answer:

Sets A and B are not equal.

Step-by-step explanation:

Given two sets A={-7,5,2} and B= {3√125,√4,√49}

we have to find are these two sets A and B equal

A={-7, 5, 2}

B={3√125,√4,√49}

$\sqrt125=\sqrt{25\times 5}=5\sqrt5$

$\sqrt4=2$

$\sqrt{49}=7$

Hence, the set B is

B={3√125,√4,√49}={15√5,2,7}

A={-7, 5, 2}

As the value of coordinates x,y and z are not equal implies the set are not equal.

Hence, A≠B
