18 * * * * * No! 2*3*5 = 30
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.
2^2 x 3 x 5
It is: 2^2 times 3^2 = 36
It is: 2^4 times 3^2 = 144
18 * * * * * No! 2*3*5 = 30
Prime numbers don't factorize; they're already prime.
Think of the "ex" in index as meaning exponent. Write the prime factorization with exponents. 216 = 23 x 33
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.
2^2 x 3 x 5
Well, isn't that just a happy little question! To write 160 as a product of its prime factors, we can express it as 2^5 * 5. In index form, this would be written as 2^5 * 5^1. Just remember, there are no mistakes, only happy little accidents in math!
648 expressed as a product of its prime factors in index form is 2^3 times 3^4
The prime factors of 45 are 3 and 5.
