a = 7, when F = 56
Explanation:
From the given question,
F = xa ............. 1
⇒ x =
................. 2
when F= 72 and a = 9,
substitute the values of F and a in equation 2, to have;
x =![\frac{72}{9}](/tpl/images/1028/7526/5e66d.png)
= 8
x = 8
Thus, the value of a when F = 56 can be determined as follows;
From equation 1,
a =
................... 3
=![\frac{56}{8}](/tpl/images/1028/7526/4a49d.png)
= 7
a = 7
The value of a is 7.
