Answer:

$3 {w}^{5} \times {7w}^{5} \\ \\ = (3 \times 7)( {w}^{5} \times {w}^{5} ) \\ \\ = 21( {w}^{5} \times {w}^{5} )$

from law of indices:

${x}^{a} + {x}^{b} = {x}^{(a + b)}$

therefore:

$= 21 \{ {w}^{(5 + 5)} \} \\ \\ ={ \boxed{ 21 {w}^{10} }}$

Answer:

512 cm^3

Step-by-step explanation:

Divide 384 by 6 to find the surface area of one face of the cube. 384/6 = 64.

Find the square root of 64 to find both the length and width of the square. They are equal in a square. $\sqrt{64}$ = 8 = x

Volume = xyz or x^3

8^3 = 512
