Answer:

a=4, b = 7, c = 3
Simplified: a = 4, b = 343

Explanation:

in Fractional exponents:


x^{(1)/(n) } = \sqrt[n]{x} (The n-th Root of x)

Another way to explain it: the numerator is the power and the denominator is the root

for example:


4^(1)/(2) = √(4) = 2

Another example:


8^{(1)/(3) } = \sqrt[3]{8}=2

This problem:


7^{(3)/(4) } = (7^(3) )^{(1)/(4) } = \sqrt[4]{7^(3) } = \sqrt[4]{343}

Answer:

Q 1 a = 4, b = 7, c = 3

Q 2 a = 4, b = 343

Explanation:

Question 1:


x^{(y)/(z)} = \sqrt[z]{x^y}

using the above equation we can compare and get the answer,

a = 4, c = 3, b = 7

Question 2:

in SIMPLIFIED, we can evaluate
7^3 and convert it in the required form


7^{(3)/(4)} = \sqrt[4]{7^3}

a = 4, b = 343

Hopefully this answer helped you!!
