Question

simplify
[√(x+16)]-4

Answer 1

why dont u try first

Answer 2

rewrite (srqt(x+16))^-4

Answer 3

[(x+16)^1/2]^-4

Answer 4

[x+16]^(1/2*-4)
[x+16]^(-4/2)
[x+16]^(-2)

Answer 5

[sqrt(x-16)]-4
@aj01 this is the problem ☺

Answer 6

okay

Answer 7

I dont know how to solve it, pls help.

Answer 8

i did solve it for you above

Answer 9

[(x+16)^1/2]^-4
[x+16]^(1/2*-4)
[x+16]^(-4/2)
[x+16]^(-2)

Answer 10

that -4 is not an exponent, it comes after the radical.

Answer 11

i c

Answer 12

[(x+16)^.5]-4
adding 16/16 to x
[(16/16x+16)^.5]-4
[(16(x/16+1))^.5]-4
4(x/16+1)^.5-4
4(sqrt(x/16-1)^.5-1)

Answer 13

i think the sqrt(x+16)-4 is simpler

Answer 14

\[\sqrt{x+16}-4=(x+16)^{\frac{1}{2}}-4=(x+16)^{\frac{2}{4}}-2^2=((x+16)^{\frac{1}{4}})^2-2^2\]
Now apply
\[a^2-b^2=(a+b)(a-b)\]

Answer 15

curious... is it to the power of (-4) or is it just.... minus 4...?
