(3xy)^2x^4y simplifying an expression

DerKrebs [107]

Answer:

$36x^6y^3$

Step-by-step explanation:

The problem needs application of law of indices

$1. (xy)^m = x^my^m$

This means common power for terms can be applied to each term individually.

$x^a x^b = x^(a+b)\\$

Separate power for the terms having same base can be added together.

_______________________________________________________

we will be using these law of indices in the problem

$(3xy)^2x^4y \\=> 3^2x^2y^2x^4y$

applied the first rule of indices as mentioned above

$3^2x^2y^2x^4y\\=>9*x^(2+4)4y^(2+1)\\=>9*4x^6y^3\\=>36x^6y^3$

applied the second rule of indices as mentioned above

Thus, simplified form of (3xy)^2x^4y is $36x^6y^3$ .

Help! Please smart people

LenKa [72]

225 is about 200

12 is about 10.

To put the same in each vase, we divide.

200÷10=20

So the answer for the best estimate would be D, 20 flowers.

When a number decreased by 10% the result in 63. What is the number?

Ugo [173]

The number is 69.3 because percent means 0.01, so 10 x 0.01 = 1.1
so 1.1 x 63 = 69.3. you can also do 63 x 10% = 69.3.
