Answer 2

To calculate the given expression with the specified values of a and b, simply substitute a = 7 and b = 2 into the expression and perform the calculations step by step:

(a^2 * b^(1/2))^(1/4) / (a^(1/2) * b^(9/8))

Substitute a = 7 and b = 2:

(7^2 * 2^(1/2))^(1/4) / (7^(1/2) * 2^(9/8))

Now, let's calculate each part of the expression:

(7^2 * 2^(1/2))^(1/4) = (49 * √2)^(1/4) = (49 * 1.41421356237)^(1/4) ≈ 6.23191480762

(7^(1/2) * 2^(9/8)) = (√7 * 2^(9/8)) ≈ (2.64575131106 * 2.82842712474) ≈ 7.48331477363

Now, divide the results:

6.23191480762 / 7.48331477363 ≈ 0.83254014448

So, when a = 7 and b = 2, the given expression evaluates to approximately 0.8325.
