I’m so lost guys lol send help

Answer 1

$\large{ \tt{❃ \: EXPLANATION}} :$

• Firstly , You'll have to know the formula of a³ - b³ i.e a³ - b³ = ( a - b ) ( a² + ab + b² )

• What's the cube root of 1000 ? - It's 10 ! How ?

1. $\sqrt[3]{1000} = \sqrt[3]{ \underline{10} \times \underline{ 1 0} \times \underline{ 10} } = \boxed{10}$

$\large{ \tt{❁ \: LET'S\: START}} :$

$\large{ \bf{ ❀ \: \ {x}^{3 } - 1000}}$

- Write the number into the exponential form with the exponent 3 :

$\large{ \bf{↦ {x}^{3} - {10}^{3} }}$

- Here , Suppose ' x ' as ' a ' & ' 10 ' as ' b '. Use the formula of a³ - b³ :

$↦{ \large{ \bf{(x - 10)( {x}^{2} + x \times 10 + {10}^{2} }}})$

$↦ \boxed{\large{ \bf{(x - 10)( {x}^{2} + 10x + 100) }}}$

• Hence , Second option is the correct choice !
