Question

-8+5w^4=28 what is w=

Answer 1

w= ± ⁴√36/5

Explanation:

-8+5w^4=28

=>5w⁴=28+8

=>w⁴=36/5

=>w= ± ⁴√36/5

Answer 2

w = ±
`\sqrt[4]{36/5}`

Explanation:

-8+5w^4=28

You can regroup it:

5w^4 - 8 = 28

Add 8 to both side:

5w^4 = 28 + 8

5w^4 = 36

Divide both side by 5:

5w^4/5 = 36/5

w^4 = 36/5

Take the 4 root of both sides:

w = ±
`\sqrt[4]{36/5}`

Hope this help you :3
