Answer:
8x^9
Step-by-step explanation:
(2x^3)^3 =
First, to raise a product to an exponent, raise eve3ry factor to the exponent.
Second, to raise a power to a power, multiply powers.
= 2^3 * (x^3)^3
= 8 * x^9
= 8x^9

Answer:
19.79 ft
Step-by-step explanation:
Given data
We are given that the dimension of the room is
Length= 14ft
Width= 14ft
Required
The Diagonal of the room
Applying the Pythagoras theorem we have
D^2= L^2+W^2
substitute
D^2= 14^2+14^2
D^2= 196+196
D^2= 392
D= √392
D= 19.79 ft
Hence the distance from one corner to the other is 19.79 ft
