Question

diya h. 7y×6=yyy answer this question Diya Hai 7 Y multiply 6 is equal to y y y ​

Answer 1

"y = 0 or ± $\sqrt{42}$"

Step-by-step explanation:

We have,

7y × 6 = y·y·y

⇒ 42y = $y^{3}$

⇒ $y^{3}$ - 42y = 0

⇒y($y^{2}$ - 42) = 0

⇒ y = 0 or ($y^{2}$ - 42) = 0

⇒ ($y^{2}$ - 42) = 0

⇒ $y^{2}$ = 42

⇒ y = ± $\sqrt{42}$

Hence, y = 0 or ± $\sqrt{42}$.
