The sqrt of 3(8^sqrt of 7 - 4^sqrt of 3)

To simplify the given expression, let's break it down step by step.

First, let's simplify the exponents by applying the basic exponent rules:

√(3(8^√7 - 4^√3))

= √(3(8^√7/4^√3)) [Using the rule: a^(m-n) = a^m / a^n]

= √(3((2^3)^√7/(2^2)^√3)) [Expressing 8 and 4 as powers of 2]

= √(3(2^(3√7)/(2^(2√3))))

= √(3 * (2^(√7 * 3)/(2^(√3 * 2)))) [Using the rule: (a^m)^n = a^(m * n)]

= √(3 * (2^(3√7 - 2√3))) [Using the rule: a^m / a^n = a^(m-n)]

Now, let's simplify the expression inside the square root:

= √(3 * 2^(3√7 - 2√3))

Since we cannot simplify any further, this is the simplified expression for √(3(8^√7 - 4^√3)).
