Question number(v)

Answer 1

Hey mate! here's your answer!
________________________

solution :-

(v)

${x}^{ - \frac{7}{2} } \times 2{x}^{ - \frac{1}{2} }$

so, we know that,

when we multiply two numbers or variable whose base are same, so their exponents add.

$= > 2{x}^{ \frac{ - 7}{2} + (\frac{ - 1}{2}) }$

$= > 2{ x }^{ \frac{ - 7 - 1}{2} }$

$= > 2{x}^{ \frac{ - 8}{2} }$

$= > 2{x}^{-4}$

thus , in positive form, it can be written as ,

$= > { \frac{2}{{x}^{4}} }$

hope you understood!
