Question

Hey smarties solve it please
2nd one


Thank you ☺

Answer 1

Answer:

y = 3

Step-by-step explanation:

Given: √1369 + √0.0615 + x = 37.25

⇒ 37 + √0.0615 + x = 37.25

⇒ √0.0615 + x = 37.25 - 37

⇒ √0.0615 + x = 0.25

On squaring both sides, we get

⇒ (√0.0615 + x)² = (0.25)²

⇒ 0.0615 + x = 0.0625

⇒ x = 0.0625 - 0.0615

⇒ x = 0.001.

Given: x = (1/10^y)

⇒ 0.001 = (1/10^y)

⇒ (1/10³) = (1/10^y)

On comparing both sides, we get

⇒ y = 3.

Therefore, the value of y = 3.

Hope it helps!

Answer 2

Answer:

y = 3

Step-by-step explanation:

Given: √1369 + √0.0615 + x = 37.25

⇒ 37 + √0.0615 + x = 37.25

⇒ √0.0615 + x = 37.25 - 37

⇒ √0.0615 + x = 0.25

On squaring both sides, we get

⇒ (√0.0615 + x)² = (0.25)²

⇒ 0.0615 + x = 0.0625

⇒ x = 0.0625 - 0.0615

⇒ x = 0.001.


Given: x = (1/10^y)

⇒ 0.001 = (1/10^y)

⇒ (1/10³) = (1/10^y)

On comparing both sides, we get

⇒ y = 3.


Therefore, the value of y = 3.
