Answer:
a=9 ( I think)
Step-by-step explanation:
we know that sqaure roots always equal to the base
(like 3^2 =9 or (root of 5)^2 equals to 5)
so I used "a" as a variable
so we must set it up at a^2= 9^3
of course, you must solve a, by sqaure rooting it
[tex] \sqrt{ {a }^{2} } = \sqrt{ {9}^{3} } [/tex]
thus, leaving it
a= 9^(3/2)
but take my answer with a grain of salt ^^"
