(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 $36x^6y^3$ .

the sum of the measures of the three of a angles of triangle is 180. In a triangle, the measures of three angles are x,x-5 and x

Veseljchak [2.6K]

x + x-5 + x +23 = 180

combine like terms:

3x +18 = 180

subtract 18 from each side:

3x = 162

divide both sides by 3

x = 162 / 3 = 54

Angle x = 54 degrees

Angle x-5 = 54-5 = 49 degrees

Angle x +23 = 54 +23 = 77 degrees
