Step-by-step explanation:
<u>Points to remember</u>
<u>Identities</u>
ᵃ√x = = x¹/ᵃ
√x = x¹/²
(xᵃ)ᵇ = xᵃᵇ
<u>To find the correct option</u>
It s given that,
(⁴√9)¹/² ˣ
By using the above identities we can write,
(⁴√9)¹/²ˣ = (9¹/⁴)¹/²ˣ [ since ⁴√9 = 9¹/⁴]
= 9⁽¹/⁴ * ¹/²⁾ ˣ
= 9¹/⁸ ˣ
Therefore the correct answer is second option option
9¹/⁸ ˣ
6.932635
^ This is the tenths place.
