Simplifying a radical expression with an odd exponent
Simplify.
16u9\sqrt{16 u^{9}} Assume that the variable represents a positive real number.

STEP 1

1. The expression to simplify is 16u9\sqrt{16 u^{9}}.
2. The variable uu represents a positive real number.
3. Simplifying involves expressing the radical in terms of integer exponents.

STEP 2

1. Simplify the numerical part of the radical.
2. Simplify the variable part of the radical.

STEP 3

Simplify the numerical part of the radical 16\sqrt{16}.
16=4 \sqrt{16} = 4

STEP 4

Simplify the variable part of the radical u9\sqrt{u^9}.
First, express u9u^9 as a power suitable for simplification:
u9=(u4)2×u u^9 = (u^4)^2 \times u This allows us to use the property of radicals a2=a\sqrt{a^2} = a.

STEP 5

Apply the property of radicals to simplify (u4)2×u\sqrt{(u^4)^2 \times u}:
(u4)2×u=u4×u \sqrt{(u^4)^2 \times u} = u^4 \times \sqrt{u}

SOLUTION

Combine the simplified numerical and variable parts:
16u9=4×u4×u \sqrt{16 u^9} = 4 \times u^4 \times \sqrt{u} The simplified expression is:
4u4u \boxed{4u^4\sqrt{u}}
