Which expression is equivalent to ^3 square root 64a^6 b^7 c^9

sergij07 [2.7K]

Answer:

$4a^{2} b^{2} c^{3} (\sqrt[3]{b})$

Step-by-step explanation:

The given expression is :

$\sqrt[3]{(64}a^{6}b^{7} c^{9} )$

Writing 64 ,a,b,c as cubes we have:

= $\sqrt[3]{(}4^{3}( a^{2})^3( b^{2})^3.b( c^{3} )^3)$

Using radical rule we have :

= $4a^{2} b^{2} c^{3} (\sqrt[3]{b})$ .

The second option is the right answer.

Solve the equation 3x² = 108.

saul85 [17]

Answer:

x = 6

Step-by-step explanation:

First we divide both sides by 3 :

x² = 108 ÷ 3

x² = 36

Now we square root both sides :

x = √36

x = 6
