Question

tim x

(3 . x - 48) . 6 = 3³ . 3³ + 2² + 3² - 12²

Answer 1

(3x - 48). 6 = 3⁶ + 4 -135

(3x - 48) . 6 = 598

3x - 48 = 598 : 6 = 99,6

3x = 147,6

x = 49,2

Answer 2

(3x-48).6=3³.3³+2²+3²-12²

(3x-48).6=3⁶+4+9-144

(3x-48).6=729-131

(3x-48).6=598

3x-48=598:6

3x-48=\(\dfrac{299}{3}\)
3x=\(\dfrac{299}{3}\)+48

3x=\(\dfrac{443}{3}\)

\(\Leftrightarrow x=\dfrac{443}{9}\)

Answer 3

(3.x-48).6=3³.3³+2²+3²-12²

(3.x-48).6=27.27+4+9-144

(3.x-48).6=729+13-144

(3.x-48).6= 598

(3.x-48)=598:6

3.x-48=\(\dfrac{299}{3}\)

3x = \(\dfrac{443}{3}\)

=>x=\(\dfrac{443}{9}\)
