Question

The product of the common factors of 16$x^3$, -4$x^2$, $32x$ is

• A. 2x
• B. x
• C. 4x
• D. 4x²

Answer 1

The correct option is C

4x

16$x^3=2\times 2\times 2\times 2\times x\times x\times x$

- 4$x^2=-1\times 2\times 2\times x\times x$

$32x=2\times 2\times 2\times 2\times 2\times x$

The common factors are $2,2,x$ Their product = $4x$
