Answer 1

Answer:

Step-by-step explanation:

cube root of 64^-2

= cube root of 1 / 64

= cube root of 1 / 4^3

= 1 / 4 or 4^-1

Answer 2

Answer:

$\LARGE{ \underline{\underline{\red{\bf{Answer↝\:}}}}}$

= 0.046875

Let's solve this step by step :

3 \sqrt{ {64}^{ - 2} }3

64 −2

First we simplify the root --->

√64^(-2)

For this, we must reduce the index of the radical and exponent with 2

| 64^(-1) |

Now calculate the absolute value. Which is always positive.

| 64^(-1) |

64^(-1)

Now let's get back to the question.

3 \sqrt{ {64}^{ - 2} }3

64

−2

=3 \times {64 }^{ - 1}3×64

−1

= 3 * 1/64

= 3/64 = 0.046875
