Answer:
Therefore the value of a is 3.78.
Step-by-step explanation:
Indices Rule:
Given that,
(a,b) satisfies the two equations
.........(1)
and
.........(2)
From equation (1) we get
Squaring both sides
......(3)
Divide equation (3) by (2) we get
Now plug the value of b in equation (1)
Therefore the value of a is 3.78.
