Step-by-step explanation:
Let the equation is
............ (1)
Putting the values of point A in equation (1) as follows.
Putting the values of point B in equation (1) as follows.
Now, divide the equation (2) by equation (3) as follows.
Cancelling out with common factors, the equation will be written as follows.
4 =![\frac{b^{-1}}{b^1}](/tpl/images/0307/8766/233f9.png)
4 =![\frac{1}{b^1 \times b^{1}}](/tpl/images/0307/8766/08157.png)
4 =![\frac{1}{b^2}](/tpl/images/0307/8766/94c5c.png)
or,![b^{2} = \frac{1}{4}](/tpl/images/0307/8766/bc3a9.png)
Taking square root on both the side, we get
b = ±![\frac{1}{2}](/tpl/images/0307/8766/9cdae.png)
Case 1. Place the value of b = +
in equation (3) as follows.
a = 16
Case 2. Place the value of b = -
in equation (3) as follows.
8 =![a \times (\frac{-1}{2})^{1}](/tpl/images/0307/8766/318bb.png)
a = - 16
