Answer

12\frac{1}{2}

Step-by-step solution

4 steps
  1. Simplify the numerator by combining like terms.

    2x3+8x3=(2+8)x3=10x32x^3 + 8x^3 = (2+8)x^3 = 10x^3
  2. Simplify the denominator.

    First, evaluate the squared term.

    (2x)2=22x2=4x2(2x)^2 = 2^2 x^2 = 4x^2

    Now, multiply this by 5x5x:

    (5x)(4x2)=5⋅4⋅x⋅x2=20x1+2=20x3(5x)(4x^2) = 5 \cdot 4 \cdot x \cdot x^2 = 20x^{1+2} = 20x^3
  3. Substitute the simplified numerator and denominator back into the expression.

    10x320x3\frac{10x^3}{20x^3}
  4. Simplify the fraction by canceling out common terms.

    10x320x3=1020=12\frac{10x^3}{20x^3} = \frac{10}{20} = \frac{1}{2}

    The simplified expression is:

    12\frac{1}{2}
