Question

If 3(x + 2)² = 507 then x⁴ can be

a) 181/3
b) 13
c) 11
d) 17​

Answer 1

$\boxed{ \huge\bf\red{ x = 11 }}$

$\bf\underline{\underline{ Answer :- }}$

• $\bf \:3(x \: + \: 2) {}^{2} = 507$

• $\bf(x \: + \: 2) {}^{2} = \frac{507}{3}$

• $\bf \: (x + 2) {}^{2} = 169$

• $\bf(x + 2) = \sqrt{169}$

• $\bf(x + 2) = 13$

• $\bf \: x = 13 - 2$

• $\bf \: x = 11$

$\rule{10cm}{0.05cm}$

$\boxed{ \huge\bf\red{ x = 11 }}$

$\rule{10cm}{0.05cm}$

NB : As per the question , it is given to find out the
