This rational expression does not have any equivalent forms.
This rational expression does not have any equivalent forms.

9h8−6h5+4h
9 h superscript 8 baseline minus 6 h superscript 5 baseline plus 4 h

9h7−6h4+4
9 h superscript 7 baseline minus 6 h superscript 4 baseline plus 4

Answer 1

To find an equivalent form of the rational expression \( 27h^8 - 18h^5 + 12h^3 \), we can factor out the greatest common factor (GCF) from the terms.

1. The coefficients are 27, -18, and 12. The GCF of these coefficients is 9.
2. The terms all contain varying powers of \( h \). The lowest power of \( h \) in the expression is \( h^3 \).

Thus, we can factor out \( 9h^3 \):

\[ 27h^8 - 18h^5 + 12h^3 = 9h^3(3h^5 - 2h^2 + 1) \]

Now we can rewrite it in different forms. However, if we simplify further by factoring or combining terms while maintaining equivalent expressions, we need to verify the provided options:

1. Option A: \( 9h^7 - 6h^4 \) does not represent the original expression.
2. Option B: This says the rational expression has no equivalent forms, which is incorrect because we just factored it.
3. Option C: \( 9h^8 - 6h^5 + 4h \) does not match the expression.
4. Option D: \( 9h^7 - 6h^4 + 4 \) does not represent the original expression.

None of the provided options are correct. The simplest equivalent form based on our factoring could be stated as:

\[ 9h^3(3h^5 - 2h^2 + 1) \]

If you need to select one despite them being incorrect, you should note that no accurate equivalent representation was provided in your choices.
