Which of the following is a true statement?
docker41 [41]

Answer:

C) To square a number, multiply the number by itself.

Step-by-step explanation:

A) is incorrect because square roots are made by multiplying the number to itself.

2 × 2  is the same as 2²

3 × 3 is the same as 3²

4 × 4 is the same as 4²

2² = 4

3² = 9

4² = 16

B) is incorrect because the inverse of squaring is finding the square root.

2² inverse is √4

3² inverse is √9

4² inverse is √16

D) is incorrect because perfect squares can be odd or even

A perfect square is a number made by squaring a whole number.

4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.

36^6 or 2176782336

Step-by-step explanation: if you multiply 10^2 would equal because you would multiply 10 by 10 and 4^3 would equal 64 because you would have to multiply four 3 times (4 x 4 x 4) and you subtract 100 and 64 (100 - 64) and you get 36 BUT, the question says "Give your answer as APO 6, so you put your answer as 36^6 or 2,176,782,336
