Question

Solve the equation or formula for the indicated variable.
a=21^3w, for w

a. w=a/21^3
b. w=a/21
c. w=1^3/2a
d. w= a/3-2

Answer 1

I'm sorry
\[a= 21^{3w}\]

Answer 2

it can't be that because none of the answer involve a log
must be \[\huge a=21^3w\]

Answer 3

So the answer is A

Answer 4

in which case
\[w=\frac{a}{21^3}\]
