What is the simplest form of√1,764?
a. 32(72)
b. 22(32)(72)
c. 21
d. 42

The simplest form of√1,764 is 42.

Step-by-step explanation:

We have to write in simplest form. It can be simplified by taking its square root. If a number is multiplied with itself such that we get a original number, then that number is called square root.

For example, 3 and -3 are square roots of 9. In this case, the square root of 1764 can be determined using factorization method also.    

Factors of 1764 are : 2 × 2 × 3 × 3 × 7 × 7. So, in simplest form 1764 is equal to 42.

Hence, the correct option is (d) " 42 ".

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
