Answer:
The value is 5 1/2 ⇒ second answer
Step-by-step explanation:
* At first we must simplify each radical and then add the terms
- To simplify the cube root lets change the number under it
to a number with power of 3 and then change radical to
a rational exponent
∵ ∛x = x^1/3
∵ 343 = 7 × 7 × 7 = 7³
∴∛343 =
* WE will use the rule ⇒
∴
* We will do the same with ∛(-8)
∵ -8 = -2 × -2 × -2 = (-2)³
∴∛(-8) =
* Lets solve the problem
# ∛343 + 3/4 (∛-8) = 7 + (3/4) × (-2) =
7 + (-3/2) = 11/2 = 5 1/2
* The value is 5 1/2
