Question

Need help!! I don’t know the answer in red. It's not 2.

Answer 1

Answer: a=-8 and b=-2

Step-by-step explanation:

What is simple form of $\sqrt[3]{x^{10} }$

=  $\sqrt[3]{(x^{9})(x) }$

Now, When x = -2

Comparing $a\sqrt[3]{b}$ with $x^{3}\sqrt[3]{x}$

We get,

$a = x^{3}$

$a = -8$

Now, $b = x = -2$
