Find the Square root. √576 The positive square root of 576 is 24 because 24*24=576.
Simplify : √(1/9) √1/√9. √1 is 1 because 1*1=1; √9 is 3 because 3*3=9. And the answer is 1/3.
Find the square root. -√36 36 is a perfect square when there is a non negative real number that multiplied by itself gives 36. 36 is a perfect square: 6*6=36. "-" means opposite so the answer is -6.
Simplify by factoring. √x<sup>12</sup> √x<sup>6*2</sup>. 2 goes with 2 from the radical and the answer is x<sup>6</sup>
Approximate the square root to three decimal places. √10 Since the radicand, 10, cannot be written as a perfect square, √10 is an irrational number. Use the calculator to approximate. 10^1/2 is approximately equal with 3.162.
Find the root. <sup>3</sup>√8 Write 8 as a perfect cube: 2*2*2=2<sup>3</sup>. Which means that the root of <sup>3</sup>√8 is 2.
Simplify. <sup>3</sup>√(x<sup>12</sup>) Simplify the radical: <sup>3</sup>√x. Summarize: x<sup>12/3</sup>=x^4
Simplify. √(-2<sup>2</sup>) (a^n)^1/n. If n is an even positive integer, we have |a|. If n is an odd integer, we have a. Here we have |a|. The value of a is -2. |-2|=2.
Simplify the radical. <sup>3</sup>√(-8x<sup>6</sup>*y<sup>12</sup>) (a^n)^1/n. If n is an even positive integer, we have |a|. If n is an odd integer, we have a. Here we have |a|. Find the number which raised at 3rd power is -8. Simplify: <sup>3</sup>√(-8x<sup>6</sup>*y<sup>12</sup>)=-2x<sup>2</sup>*y<sup>4</sup>
If g(x)=<sup>3</sup>√(x-10), find g(37). Replace x in the function with 37. g(37)=<sup>3</sup>√(37-10). Simplify: g(37)=<sup>3</sup>√27. Simplify,if possible. g(37)=3.
Find the square root. √81 The positive square root of 81 is 9 because 9*9=81.
Find the square root. -√400 400 is a perfect square when there is a non negative real number that multiplied by itself gives 400. 400 is a perfect square: 20*20=400. "-" means opposite so the answer is -20.
Approximate the square root to three decimal places. √387 Since the radicand, 387, cannot be written as a perfect square, √387 is an irrational number. Use the calculator to approximate. 387^1/2 is approximately equal with 19.672.
