Question

what are the basic of fundamental measurement​

Answer 1

Answer:

The square root of a number is the number that when multiplied to itself gives the original number as the product.

169 = a × a = a2

Thus, a = √169 = √(13 × 13)

13 × 13 = 169 or -13 × -13 = 169.

Thus the square root of 169 is +13 or -13.

This shows that 169 is a perfect square.

Explanation:

The square root of a number is the number that when multiplied to itself gives the original number as the product.

169 = a × a = a2

Thus, a = √169 = √(13 × 13)

13 × 13 = 169 or -13 × -13 = 169.

Thus the square root of 169 is +13 or -13.

This shows that 169 is a perfect square.

Answer 2

Answer:

Rasch analysis operationalizes Fundamental Measurement based on ordered qualitative observations. Fundamental measures are estimated directly from observation (such as height and weight), rather than derived indirectly by means of other measures (such as density and electrical resistance).
