No. The square of a rational is rational. 1.28 = 128/1000 → 1.28² = (128/100)² = 128²/100² = 16384/10000 = 1.6384

The number is the square root of 128 times the square root of 128 = 128

It's the other way around. The square root of 128 lies between 11 and 12.

128 = 8*8*2 so sqrt(128) = sqrt(8*8*2) = sqrt(8*8)*sqrt(2) = sqrt(82)*sqrt(2) = 8*sqrt(2) since the sqrt of a square is the number itself.

8 times [ square root of 2 ] .

128 = 64 x 2 so sqrt = 8 x root 2 or "8 root 2" 128 = 2^7 = 2^6 × 2 → √128 = √(2^6 × 2) = √(2^6) √2 = 2^3 √2 = 8 √2

a square area will be 8x8=64. Formula is a2 + b2 = c2. In other words the square root of (8x8 + 8x8) 128 which is 11.31371

In a triangle ABC, when hypotenuse is 128 unit which is right angled at A. By phythagoras theorem H square = P square + B square root of hypotenuse = ROOT of 8square + root of 8square it means other two sides are equal therefore . assuming the sides equal to x we have 2x square=128 x square= 64 x = -+8 but length is always positive. therefore other two sides = x= 8

225 is, but 128 isn't . 225 is the square of 15. 128 is double the square of 8, and half the square of 16.

-1281/2 = -11/2 * 1281/2 = i * 1281/2 = i * 641/2 * 21/2 = i * 8 * 21/2Short of now calculating the value and writing this as a multiple of i this is as simplified as it can be.The square root of -128 = 8i * 21/2(note: x1/2 means "the square root of x").

no- 121 is the square of 11 and 144 is the square of 12 and there are no squares in between but that is where 128 lies .

It is: 128/4 = 32 and 32*32 = 1024 square cm
