For instance, the product of a number 2 by itself is 4. In this case, 4 is termed as a perfect square. A square of a number is denoted as n × n. Similarly, the exponential notation of the square of a number is n 2, usually pronounced as “n” squared.
A perfect square is a number made up by 2 exact identical numbers multiplying each other, and a perfect cube is the same but 3 exact identical numbers.
The first perfect cube is 1, as 1 x 1 x 1 = 1. Perfect square : 1,4,9,16,25,36,49,64,...
So, the 7th perfect square is 49.
Sum of 1st perfect cube and 7th perfect square is 1 + 49 = 50.
