Question

Evaluate radical expression challenge

Answer 1

Answer: 1 and 5/647 or 1.00779

Step-by-step explanation:

10x64+7=647

5x64+1=642

647/642=1.00779

Answer 2

8

Explanation:

Using the rules of exponents

`(a^(m) )/(a^(n) )` =
`a^((m-n))` and
`a^{(1)/(2) }` =
`√(a)`

Given

`\frac{64^{(7)/(10) } }{64^{(1)/(5) } }`

=
`64^{((7)/(10)-(1)/(5)) }`

=
`64^{(1)/(2) }` =
`√(64)` = 8
