The expression with a rational exponent of the seventh root of x to the third power is x to the three sevenths power ⇒ answer A
Step-by-step explanation:
Let us explain how to change the radical expression as an expression
with a rational exponent
1. Find the number of the root and make it the denominator of the
fraction exponent
2. Find the power of the term under the radical and make it the
numerator of the fraction exponent
Examples:
So
∵ the radical expression is the seventh root of x to the third power
∵ seventh root =
∵ x to the third power = x³
∴ seventh root of x to the third power =
Let us change it to the rational exponent
∵
∵
∴ m = 7 and n = 3
∴ =
∵ is x to the three sevenths power
∴ is x to the three sevenths power
The expression with a rational exponent of the seventh root of x to the third power is x to the three sevenths power

Answer: 18%
Step-by-step explanation: Add 36 + 14 = 50
Then 36*50/100=18
A certain four-cylinder combination lock has 50 numbers on it.
It is a four cylinder combination lock
Each cylinder has 50 numbers
So we have to choose 4 numbers for 4 cylinders
_____ , ______ , ______, _____
you turn to a number on the first cylinder
We have 50 numbers so we have 50 combinations
__50___ , ______ , ______, _____
Repetitions are allowed so we do the same for remaining three
50 , 50 , 50 , 50
50 * 50 * 50* 50 = 6250000
There are 6250000 different lock combinations .
Answer:
211.7 Per Day 8.8 Per Hour
Step-by-step explanation:
First you do 1482/7 which gives you an average for each day (211.7)
Then you take 211.7 and divide that by 24 because there are 24 hours in a day and doing so would give you 8.8
