Question

do you agree with solution a)x power -3×x power -5=x power 15.and b)3x power -1=1/3x. ​

Answer 1

Answer:

both answers are wrong

Step-by-step explanation:

${x}^{ - 3} \times {x}^{ - 5} = {x}^{ - 3 - 5} = {x}^{ - 8}$

$3 {x}^{ - 1} = \frac{3}{x}$

If you meant the second question as (3x) power-1, then it is right.

${(3x)}^{ - 1} = \frac{1}{3x}$
