1 answer:

5 0

3 sqrt(-32) x^4 y^6
sqrt(-32) = sqrt(-1) sqrt(32) = i sqrt(32):
3 i sqrt(32) x^4 y^6
sqrt(32) = sqrt(2^5) = 2^2 sqrt(2):
3 i×2^2 sqrt(2) x^4 y^6
2^2 = 4:
3 i×4 sqrt(2) x^4 y^6
3×4 = 12:
Answer: 12 i sqrt(2) x^4 y^6

Pleas someone help me with this it's my last question

Answer:

we need to find out if the following get x = 2 as a final product

-2(x-4) = 4

-2x + 8 = 4

-2x = -4

x = 2

so it is a solution

26/x = 13

26 = 13x

x = 26/13

x = 2

so it’s a solution

-3.8x = -7.4

x = 7.4/3.8 ≠ 2

you get ≈ 1.95

so it’s not a solution

4(x-1) - 3(x-2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -10

so it’s not a solution

Answer:

$5y^{6}\sqrt{2}$

Step-by-step explanation:

We want to simplify:

$\sqrt{50y^{12}}$

We rewrite as:

$\sqrt{2\times25 \times (y^{6})^2}$

We split the radical sign to obtain:

$\sqrt{25} \times \sqrt{(y^{6})^2} \times \sqrt{2}$

Simplify the square root for the perfect squares to get:

$5y^{6}\sqrt{2}$

Therefore the simplified form is: $5y^{6}\sqrt{2}$
