Use the order of operations to simplify the expression.

\( 6 ^ { 2 } - 27 \div 3 ^ { 2 } \cdot 4 - 7 \)

\( 6 ^ { 2 } - 27 \div 3 ^ { 2 } \cdot 4 - 7 = \square \)

Evaluate the expression without using a calculator.

\( 128 ^ { \frac { 4} { 7} } \)

Rewrite the expression using a radical.

\( 128 ^ { \frac { 4 } { 7 } } = \square \)(Do not evaluate.)

Evaluate

\( 128 \frac { 4 } { 7 } = \square \)(Simplify your answer.)

Evaluate the expression without using a calculator.

\(128 ^ { \frac { 4 } { 7 } } \)

Rewrite the expression using a radical.

\(128 ^ { \frac { 4 } { 7 } } = \square \)(Do not evaluate.)

Evaluate.

\( 128 ^ { \frac { 4 } { 7 } } = \square \) (Simplify your answer.)

Perform the indicated computation. Write the answer in scientific notation.

\( ( 5.2 \times 10 ^ { - 9 } ) ( 3 \times 10 ^ { - 6 } ) \)

\( ( 5.2 \times 10 ^ { - 9 } ) ( 3 \times 10 ^ { - 6 } ) = \square \)

(Use the multiplication symbol in the math palette as needed.\( ) \)

Use the product rule to simplify the following expression.

\( \sqrt { 45 x ^ { 2 } } \)

\( \sqrt { 45 x ^ { 2 } } = \square \)

(Type an exact answer using radicals as needed.)
