1000000 x 3.2 = 3200000
Expressed in figures, this is equal to 320,000.
3156770 = 3200000 to the nearest hundred thousand.
You can get a decimal approximation with a calculator, with Excel, etc. But if you want to keep it as a square root, the "standard form" is considered to be one that has no square roots in the denominator. In this case, to get rid of the square root in the denominator, you multiply both numerator and denominator by the square root of 5, with the following result: 3 / root(5) = 3 root(5) / root(5) x root(5) = 3 root(5) / 5 That is, three times the square root of 5, divided by 5.
zero
The 5th root is 20.
3200000
The answer is 3200000.

3.2 x 10^6
1000000 x 3.2 = 3200000
Expressed in figures, this is equal to 320,000.
Three million two hundred thousand.
3200000
3,200,000/100 320,000/10 32,000/1
You look for the largest perfect square, and take it out. In this case: root(125) = root(25 x 5) = root(25) x root(5) = 5 x root(5).
