(3x^2a - 4y^a z^3a) ^2 ...?
shusha [124]
The answer is 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ


(a - b)² = a² - 2ab + b²
(3x²ᵃ - 4yᵃz³ᵃ)² = (3x²ᵃ)² - 2 * 3x²ᵃ * 4yᵃz³ᵃ + (4yᵃz³ᵃ)² =
                         = 3²x²ᵃ*² - 2 * 3 * 4 x²ᵃ * yᵃz³ᵃ + 4²yᵃ*²z³ᵃ*² =
                         = 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ

Let x be the population of Nevada.

We are given population of Virginia is 2.8 million less than 4 times the population of Nevada.

\therefore 4x-2.8=8

      4x=8+2.8

      4x=10.8

      x=\frac{10.8}{4} =2.7

The first step is to on both sides.

add 2.8

The second step is to on both sides.

divide 4

The population of Nevada is million.
