If the number can be written as 2*3*5 it cannot be prime!
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
24 x 3 x 5 = 240.
18 * * * * * No! 2*3*5 = 30
Prime numbers don't factorize; they're already prime.
Index form is where a number is expressed as the exponents of its prime factors. At the moment, you have it as its prime factors. We have two 3s, so that can be given as 32 and we have four 4s, so that can be given as 44. Thus 3x3x4x4x4x4 in index form is 32x44
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
2x2x2x2x2x5
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.
