Answer 2

Step-by-step explanation:

ii) 11 to the power 5/2 divided by 11 to the power 3/2.

=

$11 {}^{ \frac{5}{2} } \times 11 {}^{ \frac{ - 3}{2} }$

=

$11 {}^{ \frac{5}{2} + \frac{ - 3}{2} }$

=

$11 {}^{ \frac{5 - 3}{2} }$

=

$11 \frac{2}{2}$

2/2 that is 1

so, 11 to the power 1 is 11

= 11.

i) 9 to the power 3/2 multiplied by 9 to the power -4/2. ( first solving this)

=

$9 {}^{ \frac{3}{2} + \frac{ - 4}{2} }$

=

$9 {}^{ \frac{ - 1}{2} }$

= now...9 to the power -1/2 divided by 9 to the power 1/2

=

$9 {}^{ \frac{ - 1}{2} } \times 9 {}^{ \frac{-1}{2} }$

=

$9 {}^{ \frac{ - 1 - 1}{2} }$

=

$9 {}^{ \frac{-2}{2} }$

= so 9 to the power -1 is 1/9

= 1/9
