Flashcards

Square Root of 16

The square root of 16 is 4, meaning that 4 multiplied by itself equals 16.

Cube Root of 27

The cube root of a number is the value that, when multiplied by itself three times, equals the original number. The cube root of 27 is 3, because 3 x 3 x 3 = 27.

Indirect Proportion

An indirect proportion occurs when one variable increases while the other decreases, or vice versa. In this case, as the price of a product increases, the demand for it decreases, indicating an inverse relationship.

Prime Number

A prime number is a whole number greater than 1 that is only divisible by 1 and itself. 19 is only divisible by 1 and 19, so it's a prime number.

Study Notes

Mathematical Concepts

The square root of 16 is 4, indicating a number that, when multiplied by itself, equals 16.
The cube root of 27 is 3, representing a number that, when used in a multiplication of three instances (3 × 3 × 3), equals 27.
An example of an indirect (or inverse) proportion is when one quantity increases while another decreases; for example, speed and travel time in a constant distance scenario.

Number Properties

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers; examples include 2, 3, 5, and 7.
The value of pi (π) is approximately 3.14 when rounded to two decimal places, commonly used in geometry, particularly in calculations involving circles.
The smallest whole number is 0, representing the absence of value in whole number counting.
