What does the square root of 64 mean?
The square root of 64 is the number that, when squared (multiplied by itself), equals 64. The square root of 64 is 8 because 8 x 8 = 64. The square root is also expressed as the number raised to the one-half power (64^(1/2)=8).
How can you do squares and square roots?
A number is squared by multiplying it by itself, for example 8 is the square of 64 (8 x 8 = 64). Square roots are found by figuring out which number, when squared, will give the number in question, for example the square root of 64 is 8 (64 / 8 = 8).
How do you figure out the length of a line on a graph?
From point A to point B You need the X and Y value of both point A and B Formula = Distance = Square root of [(x1 + x2)2 + (y1 + y2)2] So therefore given points (1:2) and (5:-6) Square root of (1 - 5)squared + (2 + 6)squared =Square root of -4 squared + 8 squared =Square root of 16 + 64 =Square root of 80 This can be your answer but you should go a step further =Square root of 80 =Square root of 16 * 5 =4*Square root of 5
