Answer:
Choice d is correct.
Explanation:
we have given equation
6x²=54
we have to solve this equation by using square roots.
for this, divide the above equation by 6 from both sides.
after applying division the equation become
6x²/6 = 54/6
x² = 9
now applying square root on both sides.
√x² = √9
so the final equation become:
x = ± 9
x = ± 9 is the required answer.
