Question

ok , hello please answer
If 3(x + 2)² = 507 then x⁴ can be

a) 181/3
b) 13
c) 11
d) 17​​

Answer 1

Answer:

3(x+2)²=507

=> (x +2)²= 507/3 = 169

=> (x+2)²= 169

=> (x+2) = +√(169) or - √169

=> (x +2) = +13 or -13

=> x = +13 -2 or -13- 2 = 11 or -15

so, value of x = 11 or -15

here, option (c) 11
