Lesson Steps

Steps Problem Solution

1

Find the indicated real \$n^(th)\$ root

\$ n = 6, a = 64 \$

2

Given surd

\$ root(n)(a) = \pm root(6)(64) \$

3

Now 64 can be written as exponential form

\$ \pm root(6)((2)^6) \$

4

Cancelled 6th root and power 6

\$ \pm (2^6)^(1/6) \$

5

Hence the required number

\$ \pm 2 \$

6

Answer

A = \$ \pm 2 \$
