Question

How do i solve 3√64 times 3√8

Answer 1

Answer:

equals 8

Step-by-step explanation:

cube root of 64 = 4 x cube root of 8 = 2

4 x 2 = 8

Answer 2

Answer:

144$\sqrt{2}$

Step-by-step explanation:

We can simplify the product using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

simplify $\sqrt{64}$ = 8

simplify $\sqrt{8}$ = $\sqrt{4(2)}$ = $\sqrt{4}$ × $\sqrt{2}$ = 2$\sqrt{2}$

The product can now be expressed as

3 × 8 × 3 × 2 × $\sqrt{2}$

= 144$\sqrt{2}$
