Question

Explain the difference between 2x3 and (2x)3.

Answer 1

2x3 is referring to 2 multiplied by 3, whereas (2x)3 is where x is a variable, and is 2 multiplied by x, then by 3

Answer 2

I assume the 3 is an exponent.

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

$(2x)^3 = 2x \times 2x \times 2x = 2 \times 2 \times 2 \times x \times x \times x = 8x^3$
