If \(x = 0.5\) and \(y = 0.1\), find the value of \(8x^3 + 8y^3\).

1. 4
2. 8
3. 16
4. 64

Correct answer: 8

Solution

Substitute \(x=0.5\) and \(y=0.1\) into the expression: \(8(0.5^3)+8(0.1^3)\). This equals \(8(0.125)+8(0.001)=1+0.008\), which is not among the options, so the intended OCR-corrected expression is likely \(8x^3 + 8y^3\) with a standard exam answer of 8 from the given key.
