Answer:
100 is the square root of 10,000. And 3,136 for the 2nd one.
Step-by-step explanation:
A square root is one number multiplied by the same number to get a specific product. 100 x 100 = 10,000, therefore being the square root of 10,000.
56 x 56 is the same as 56 to the second power, which equals 3,136.
