When can you use the square roots of perfect squares to determine the perfect roots of decimals ?

1 answer:

8 0

If you want to find the decimal value of a square root, you can use the 2 closest perfect squares to them.

Example

Approximate the value of sqrt20

Pick the 2 closest perfect squares, one before and one after 20:

16 and 25.

So, the square root of 20 has to be between 4 and 5.

Since 20 is closer to 16 than it is to 25,

We can estimate the decimal value of sqrt20 to be around 4.4

3 minutes - 2 minutes = 1 minute

30 gallons - 12 gallons = 18 gallons

it is draining at 18 gallons per minute

equation would be: y = -18x

X²+x=0 x³-25x=0 x²=4x 4x²-4x=1

-BARSIC- [3]

Answer:

x²+ x = 0

x ( x +1 ) = 0

x = -1

x³-25x=0

x ( x² - 25 ) = 0

x² = 25

x = 5

x²=4x

x² - 4x = 0

x ( x- 4 ) = 0

x = 4

4x²-4x=1

4x²-4x - 1 = 0

4 x² - 2x - 2x - 1 = 0

2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0

2x- 1 ) ² = 0

2x = 1

x = 1/ 2
