Find equivalent rational expression with denominator a2b2c2a^2 b^2 c^2 for 8+7ca2b2c\frac{8 + 7c}{a^2 b^2 c}.

STEP 1

Assumptions
1. The original expression is 8+7ca2b2c\frac{8+7c}{a^{2}b^{2}c}.
2. The desired denominator is a2b2c2a^{2}b^{2}c^{2}.
3. The numerator of the equivalent expression must be adjusted to maintain the value of the original expression when the denominator is changed.

STEP 2

Identify the relationship between the original denominator and the desired denominator.
Originaldenominator=a2b2cOriginal\, denominator = a^{2}b^{2}c Desireddenominator=a2b2c2Desired\, denominator = a^{2}b^{2}c^{2}

STEP 3

Determine the factor by which the original denominator must be multiplied to obtain the desired denominator.
Factor=DesireddenominatorOriginaldenominator=a2b2c2a2b2cFactor = \frac{Desired\, denominator}{Original\, denominator} = \frac{a^{2}b^{2}c^{2}}{a^{2}b^{2}c}

STEP 4

Simplify the factor by canceling out common terms in the numerator and denominator.
Factor=a2b2c2a2b2c=cFactor = \frac{a^{2}b^{2}c^{2}}{a^{2}b^{2}c} = c

STEP 5

Multiply the original expression by a fraction equivalent to 1 that has the factor from STEP_4 as both the numerator and the denominator.
8+7ca2b2c×cc\frac{8+7c}{a^{2}b^{2}c} \times \frac{c}{c}

STEP 6

Multiply the numerators and the denominators separately.
(8+7c)×ca2b2c×c\frac{(8+7c) \times c}{a^{2}b^{2}c \times c}

STEP 7

Simplify the expression by performing the multiplication in the numerator.
8c+7c2a2b2c2\frac{8c + 7c^2}{a^{2}b^{2}c^2}

STEP 8

Write the final equivalent rational expression with the given denominator.
8+7ca2b2c=8c+7c2a2b2c2\frac{8+7c}{a^{2}b^{2}c} = \frac{8c + 7c^2}{a^{2}b^{2}c^2}
The equivalent rational expression with the given denominator a2b2c2a^{2}b^{2}c^{2} is 8c+7c2a2b2c2\frac{8c + 7c^2}{a^{2}b^{2}c^2}.
