Question

The volume of the rectangular block is $\left(x\right)\left(x^2\right)\left(3x^3\right)$ cubic centimetres.
It can be simplified as.

• A. $3x^6$
• B. $3x^5$
• C. $3x^3$

Answer 1

The correct option is A $3x^6$

On multiplying $x$ with $x^2$, its power is raised to 3.
i.e., $x\times x^2=x^3$
then, multiplying $x^3$ with $3x^3$, its power is raised to 6.
i.e. $x^3\times 3x^3=3x^6$
