Mathematics
1 answer:
r-ruslan [8.4K]3 years ago
6 0

Answer:

OPTION - 3: -m²n³$ \sqrt{n} $

Step-by-step explanation:

We know that $ \sqrt{ab} = \sqrt{a}\sqrt{{b} $

Also, $ \sqrt{m^{2}} = m $

Now we are to simplify: $ - \sqrt{m^4n^7} $

$ \implies - \sqrt{m^4}\sqrt{n^7} $

$ \implies - \sqrt{(m^2)^2}\sqrt{n^6.n} $

$ \implies-  m^2 \sqrt{(n^3)^2.n} $

$ \implies - m^2 n^3\sqrt{n}

∴                       $ \sqrt{m^4n^7} =  -m^2n^3\sqrt{n} $

Answer:

X >>>>> Y

–1 >>>> 16

0 >>>>> 8

1 >>>>> 4

2 >>>>> 2

3 >>>>> 1

Step-by-step explanation:

From the question given above,

y = 8 × (½)ˣ

When x = –1, y =?

y = 8 × (½)ˣ

y = 8 × (½)¯¹

y = 8 × 2

y = 16

When x = 1, y =?

y = 8 × (½)ˣ

y = 8 × (½)¹

y = 8 × ½

y = 4

When x = 2, y =?

y = 8 × (½)ˣ

y = 8 × (½)²

y = 8 × ¼

y = 2

When x = 3, y =?

y = 8 × (½)ˣ

y = 8 × (½)³

y = 8 × ⅛

y = 1

SUMMARY:

X >>>>> Y

–1 >>>> 16

0 >>>>> 8

1 >>>>> 4

2 >>>>> 2

3 >>>>> 1
