How can anyone have doubt in this question. Square of 3= 9 Square of 5= 25 Square of 7= 49 Total is = 83
7
The sum of a [single] square equals the square.
The integers are 7, 8 and 9.
A sum is the addition of two or more figures. For example, 2 + 7 = 9 The square of a sum can be written as (2 + 7)2 = 92 = 81 (2 + 7)2 can also be expressed as (2 + 7) x (2 + 7) When multiplying bracketed terms, multiply the first term in the first bracket by all the terms in the second bracket and then repeat this process with the second number in the first bracket. For example, (2 + 7) x (2 + 7) = 2x2 + 2x7 + 7x2 + 7x7 = 4 + 14 + 14 + 49 = 81
Square root of 2 = 1.414213562... Square root of 7 = 2.645751311... The sum is 4.059964873...

The number is 7.
How about 7*7 = 49 because 4+9 = 13
the magic sum is 15
7
The square root of any positive integer can only be a WHOLE NUMBER or IRRATIONAL, so the square root of 7 is irrational.On the other hand, the sum of a rational and an irrational number is always irrational.
4*4=16 sum of 1+6 is 7, difference is 5 so 16 is answer
The sum of a [single] square equals the square.
It could be -7.(-7)2 + (-7) = 49 - 7 = 42.
There is only one square number from 5-15: 9. This can be written as the sum of 2 and 7, which are prime numbers.
It's not. Take 49 and 16 for example. The square root of the sum is the square root of 65. The sum of the square roots is 11.
