Whats the square root of -63 using radicand?

Answers

Answer 1

Answer:

32=3⋅3=932=3⋅3=9

9 was the square of 3. The square of -3 is 9 as well

(−3)2=(−3)⋅(−3)=9(−3)2=(−3)⋅(−3)=9

3 and -3 are said to be the square roots of 9.

All positive real numbers has two square roots, one positive square root and one negative square root. The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots

a2=a⋅a=(−a)⋅(−a)a2=a⋅a=(−a)⋅(−a)

A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.

a√a

To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.

±9√=±3±9=±3

Zero has one square root which is 0.

0√=0

Answer 2

Answer: remember
√(mn)=(√m)(√n)

so
√-63=(√-1)(√63)

63=3*3*7
√63=3√7

√-63=(3)(√7)(√-1)
√-63=(3)(√-7)
√-63=3√-7

There are 90 yellow flowers, 54 red flowers, and 36 white flowers for centerpieces. If the flowers need to be divided equally into separate centerpieces with the same number of each color of flower in each centerpiece, how many different centerpieces will there be?

Answers

Answer:

You can create the fewest centerpieces for the smallest number of any color, which is 2 centerpieces using the white flowers. Therefore, you will have 2 centerpieces with an equal number of each color of flower in each centerpiece.

Step-by-step explanation:

First, find the GCD of 90, 54, and 36:

Find the GCD of 90 and 54:

GCD(90, 54) = 18

Find the GCD of the result (18) and 36:

GCD(18, 36) = 18

So, the GCD of 90, 54, and 36 is 18.

Now, you can create centerpieces with 18 flowers of each color (yellow, red, and white) in each centerpiece. To find out how many centerpieces you can create, divide the total number of each color by 18:

Number of yellow flowers / 18 = 90 / 18 = 5 centerpieces

Number of red flowers / 18 = 54 / 18 = 3 centerpieces

Number of white flowers / 18 = 36 / 18 = 2 centerpieces
