Simplify the expression completely. -root(3)(-27)+4root(3)(8)+sqrt64 Answer:

Simplify Cube Root of -27: Simplify the cube root of -27. -root(3)(-27) = -(-3) because (-3)^3 = -27.Multiply Cube Root of 8 by 4: Simplify the cube root of 8 multiplied by 4. 4root(3)(8) = 4 * 2 because 2^3 = 8.Simplify Square Root of 64: Simplify the square root of 64. sqrt(64) = 8 because 8^2 = 64.Combine Results: Combine the results from steps 1, 2, and 3. -(-3) + 4 * 2 + 8 = 3 + 8 + 8.Perform Addition: Perform the addition. 3 + 8 + 8 = 19.

Q. Simplify the expression completely.

\newline

-\sqrt[3]{-27}+4 \sqrt[3]{8}+\sqrt{64}

\newline

Answer:

Simplify Cube Root of $-27$ : Simplify the cube root of $-27$ . $\sqrt[3]{-27} = -(-3)$ because $(-3)^3 = -27$ .
Multiply Cube Root of $8$ by $4$ : Simplify the cube root of $8$ multiplied by $4$ . $\newline$ $4\sqrt[3]{8} = 4 \times 2$ because $2^3 = 8$ .
Simplify Square Root of $64$ : Simplify the square root of $64$ . $\sqrt{64} = 8$ because $8^2 = 64$ .
Combine Results: Combine the results from steps $1$ , $2$ , and $3$ . $\newline$ $-(-3) + 4 \times 2 + 8 = 3 + 8 + 8$ .
Perform Addition: Perform the addition. $3 + 8 + 8 = 19$ .
