The expression as a product of radicals is (7^(1/2))^3 = 7^(1/2) * 7^(1/2) * 7^(1/2) .

Radical form: An expression in radical form is an expression that contains a radical symbol, which is the symbol for the square root.

A radical expression can be simplified by factoring a perfect square out of the radicand (the number under the radical symbol).

Properties of exponents:

Product rule: When multiplying powers with the same base, add the exponents.

Quotient rule: When dividing powers with the same base, subtract the exponents.

Power of a power rule:

When raising a power to another power, multiply the exponents.

Representing 7 3/4 in radical form:

To represent 7 3/4 in radical form, we can use the following steps:

Rewrite the expression as a power with a rational exponent.

7 3/4 = 7^(3/4)

Factor the radicand into a perfect square and a non-perfect square.

7^(3/4) = (7^(1/2))^3

Write the expression as a product of radicals.

(7^(1/2))^3 = 7^(1/2) * 7^(1/2) * 7^(1/2)

Therefore, 7 3/4 in radical form is 7^(1/2) * 7^(1/2) * 7^(1/2).
