Step-by-Step Solution

First, we will start with the innermost parentheses, we rewrite the expression in fraction form:

2/(8(4/(3104×8)))= 2/(8\cdot(4/(3\cdot\frac{10}{4\times8})))=

We add the 3 to the numerator of the fraction and create a multiplication expression:

2/(8(4/(3×104×8)))= 2/(8\cdot(4/(\frac{3\times10}{4\times8})))=

Again, we address the innermost parentheses, we invert the fraction to create a multiplication expression:

2/(8(4×4×83×10))= 2/(8\cdot(4\times\frac{4\times8}{3\times10}))=

We add the 4 to the numerator of the fraction and create a multiplication exercise:

2/(84×4×83×10)= 2/(8\cdot\frac{4\times4\times8}{3\times10})=

We add the 8 to the numerator of the fraction and create a multiplication exercise:

2:8×4×4×83×10= 2:\frac{8\times4\times4\times8}{3\times10}=

Now we will invert the fraction to create a multiplication exercise:

2×3×108×4×4×8= 2\times\frac{3\times10}{8\times4\times4\times8}=

We add the 2 to the numerator of the fraction and create a multiplication exercise:

2×3×108×4×4×8= \frac{2\times3\times10}{8\times4\times4\times8}=

We break down the 10 in the numerator and the 4 in the denominator into smaller multiplication exercises:

2×3×2×58×2×2×4×8= \frac{2\times3\times2\times5}{8\times2\times2\times4\times8}=

We simplify to 2 in the numerator and denominator:

3×58×4×8= \frac{3\times5}{8\times4\times8}=

We solve the multiplication exercises in the numerator and denominator from left to right:

3×58×4×8=1532×8=15256 \frac{3\times5}{8\times4\times8}=\frac{15}{32\times8}=\frac{15}{256}

Answer

15256 \frac{15}{256}
