Answer:
The simplified expression is 5/6.
Step-by-step explanation:
To simplify the expression (3a/b)^(-1) + (2b/a)^(-1), we can apply the properties of exponents.
The reciprocal of a fraction raised to a power can be obtained by taking the reciprocal of the fraction and changing the sign of the exponent.
Let's simplify step by step:
(3a/b)^(-1) + (2b/a)^(-1)
Reciprocal of (3a/b):
(1 / (3a/b))
Taking the reciprocal and changing the sign of the exponent:
(b / (3a))
Reciprocal of (2b/a):
(1 / (2b/a))
(a / (2b))
Now, the expression becomes:
(b / (3a)) + (a / (2b))
To add these fractions, we need a common denominator. The common denominator is 6ab.
Multiplying the first fraction by (2b/2b) and the second fraction by (3a/3a), we get:
((2b * a) / (2b * 3a)) + ((3a * b) / (3a * 2b))
Simplifying the numerators, we have:
(2ab / 6ab) + (3ab / 6ab)
Combining the fractions, we get:
(2ab + 3ab) / 6ab
Simplifying the numerator, we have:
5ab / 6ab
The common factors of ab in the numerator and denominator cancel out, leaving us with:
5 / 6
