Show a reciprocal numerical expression for each equation using multiplication, please!

iris [78.8K]

$\frac{2}{3}$ ÷ 4 = $\frac{2}{3} \times \frac{1}{4} = \frac{1}{6}$

$\frac{1}{8}$ ÷ 3 = $\frac{1}{8} \times \frac{1}{3} = \frac{1}{24}$

$\frac{3}{4}$ ÷ 6 = $\frac{3}{4} \times \frac{1}{6} = \frac{1}{8}$

$\frac{1}{36}$ ÷ 2 = $\frac{1}{6} \times \frac{1}{2} = \frac{1}{12}$

Solve by using factorizing method:4x²-36x+81=0

boyakko [2]

Answer:

x = 4.5

Step-by-step explanation:

4x² - 36x + 81 = 0
(2x)² - 2*2x*9 + 9² = 0 Identity a² - 2ab + b² = (a - b)²
(2x - 9)² = 0
2x - 9 = 0
2x = 9
x = 4.5
