7i is a complex number (specifically, an imaginary number).
0.42424242..... is a rational number (a repeating decimal).
0.36336333633336.... is an irrational number (a non-repeating, non-terminating decimal).
1/4 is a rational number (a fraction).
√64 is a whole number (also a natural number and an integer) since the square root of 64 is 8.
√30 is an irrational number (it cannot be expressed as a simple fraction).
-26 is an integer (a negative whole number).
To determine the type of number, we need to understand different number systems and notations.
1. 7i: This is an example of a complex number. Complex numbers consist of a real part and an imaginary part, where the imaginary part is represented by the letter "i". In this case, the real part is 0, and the imaginary part is 7.
2. 0.42424242...: This is an example of a repeating decimal. Repeating decimals are numbers that have a recurring pattern after the decimal point. In this case, the digits 42 repeat infinitely. It can be written as 0.42 with a bar over the 42 to indicate the repetition.
3. 0.36336333633336...: Similar to the previous example, this is also a repeating decimal. However, the pattern here is more complex, as digits 363 repeat. It can be written as 0.363 with a bar over the 3 to show the repetition.
4. 1/4: This is an example of a fraction or a rational number. A fraction represents a part of a whole number. In this case, 1/4 means one divided by four, which equals 0.25 in decimal form.
5. √64: This is an example of a square root. The square root of a number gives the value that, when multiplied by itself, equals the original number. In this case, the square root of 64 is 8, because 8 x 8 = 64. Therefore, √64 is the number 8.
6. √30: This is another example of a square root. However, unlike √64, the square root of 30 is not a whole number. It is an irrational number, which means it cannot be expressed as a simple fraction or decimal. The approximate value of √30 is 5.48.
7. -26: This is an example of a negative integer. Integers represent whole numbers, both positive and negative. In this case, -26 is a negative integer, indicating a value less than zero.
1. The number 7i is an imaginary number. It represents the square root of -49.
2. The number 0.42424242... is a repeating decimal. It can also be written as 42/99.
3. The number 0.36336333633336... is also a repeating decimal. It can be written as 363/999.
4. The number 1/4 is a rational number. It can be expressed as a fraction and it is equal to 0.25 in decimal form.
5. The square root of 64 is a rational number. It is equal to 8, as 8 multiplied by itself gives 64.
6. The square root of 30 is an irrational number. It cannot be expressed as a fraction and its decimal representation continues indefinitely without repeating.
7. -26 is an integer. It is a whole number that can be positive or negative, with no fractional or decimal part.
