What's the product of the first perfect square no. & 7th perfect square ?

50

Step-by-step explanation:

Perfect square: made by squaring a whole number (mulitplying a whole number by itself).

To find the nth perfect square, multiply n by itself, so n x n = n²

Therefore, the product of the first perfect square number & 7th perfect square:

1² + 7² = 1 x 1 + 7 x 7 = 1 + 49 = 50

Perfect squares are those numbers whose square roots are not irrational or rational rather than positive natural numbers.

So the formula is n^2

Sum=49+1=50

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
