x = 19

x = 52

x = 67

Answer 1

@legoauto220

Answer 2

\[(\sqrt[3]{x}-3)-5=16.\]Is this ur question?

Answer 3

x-3 is under the cubed root

Answer 4

\[\sqrt[3]{x-3}-5=16\]

Answer 5

k:)
\[\sqrt[3]{x-3}=16+5=21.\]\[\implies (x-3)=21^3.\]\[\implies x=21^3+3.\]

Answer 6

just calculate now:)

Answer 7

i know i did that but thats not one of the options above

Answer 8

\[\huge \sqrt[3]{x-3}-5=16\]
\[\huge \sqrt[3]{x-3}=21\]
\[\huge x-3=9261\]
\[\huge x=9264\]

Can't be what you meant...

Answer 9

I did the same
options are wrong:)

Answer 10

i guess its just 3 times the square root i got the answer now 52

Answer 11

x^3 = x cubed
x\(^{1/3}\) = \(\sqrt[3]{x}\) = cube root of x

Answer 12

The are NOT the same thing, at all :D

Answer 13

i know i wish i could show you how its displayed because it shows the cubed root

Answer 14

ya @cplatt688 that must be if u want answer:)
but u gt 2 question's solution
one with cuberoot & one with 3 x......

Answer 15

3 sqrt (x) = 3x^(1/2)

Answer 16

Or in clearer writing:

\[3\sqrt{x} = 3x^{1/2}\]

Answer 17

Got to always remember to be extra, extra careful with exponents (or fractional exponents, which are better known as "roots")
