What number has a prime number in index form 2x3x5?
If the number can be written as 2*3*5 it cannot be prime!
How many roots in a radical problem if the index is odd?
An odd number. In the complex field, the number of roots is the same as the index. Complex (non-real) roots come in pairs (complex conjugates) so the number of real roots will also be odd.
Are index form and standard form the same thing?
No. In the index form a number is expressed as a multiple of its prime factors whereas in the standard form it is expressed as a number between in the range [1, 10) multiplied by an integer power of 10. So, for example, 1728 in index form = 26*33 1728 in standard form = 1.728*103 The index form can only be used for integers.
What is the root of a number?
The root of a number is any number that when multiplied by a certain number of times, it becomes the original number. The number of times the root has to be multiplied is called the index of the radical. The number that it becomes after it is multiplied is called the radicand. If the index is equal to x, and the radicand is equal to y, then the root can be expressed by " y to the (1/x)th power", or "y1/x".
What are powers in mathematics?
'Power' in maths is also known as 'exponential' or 'index number'. eg. 3x^(2) / The '2' is a power/expomnential/index number.
