Question

5a^ 3 -3a^ 3 - 1 2 a^ 3​

Answer 1

Given:

$5a^{3}- 3a^{3} -12^{3}$

In this equation we have to use subtraction

$=2a^{3} -12a^{3}$

$=-10a^{3}$

Hence the final answer is -10a³

Answer 2

Given that:- $5a^ 3 -3a^ 3 - 1 2 a^ 3$

As we have to simplify the given equation,

Here, we have apply the BODMAS rule,

From that rule we have to use subtraction,

$=>5a^ 3 -3a^ 3 - 1 2 a^ 3$

$=>2a^3-12a^3$

$=>-10a^3$

The required value is $-10a^3.$
