6 to the third power would be 6x6x6 which equals 216. All you do to find the power is multiply the number by its self the amount of times it asks like 4 to the second power would be 16 and 8 to the 4 power would be 4096
It's A. Commutative property.
First you solve for X then substitute the number you got for X and then solve for Y.
Given:
Principal = $50
Rate of simple interest = 6%
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for simple interest:

Where, P is principal, r is the rate of interest in percentage and t is the number of years.
Putting
in the above formula, we get



Formula for amount is:

Where, P is principal and I is the simple interest.
Putting
, we get


Therefore, the correct option is B.
