Answer:
Step-by-step explanation:
To simplify the expression 9x^3 1/8 - 7x^1 3/8, we can combine like terms.
First, let's simplify the coefficients of the terms.
9x^3 1/8 - 7x^1 3/8
The coefficient 1/8 can be written as a decimal by dividing 1 by 8: 1/8 = 0.125.
So the expression becomes:
9x^3 * 0.125 - 7x^1 * 0.375
Next, let's simplify the powers of x:
9x^3 * 0.125 - 7x^1 * 0.375 = 1.125x^3 - 2.625x^1
Finally, we can combine the like terms:
1.125x^3 - 2.625x^1
