Write each expression in radical form

Mathematics
1 answer:
yanalaym [24]3 years ago
8 0
To write the expression in radical form, the numerator of the fraction would become the power you raise it by and the denominator becomes the root.
 
(10n )^{ \frac{3}{2} }
Becomes:
\sqrt[2]{(10n)^{3} } or just \sqrt{(10n)^{3} }

a ^{ \frac{6}{5}
Becomes:
\sqrt[5]{(a) ^{6} }

I hope this helped! ( if so give brainliest please!! )

Which function is a quadratic function? a(x) = –2x^3 + 2x – 6 b(x) = 5x^3 + 8x^2 + 3 c(x) = –8x^2 + 3x – 5 d(x) = 6x^4 + 2x – 3
Sedaia [141]

Answer:

c(x) = –8x^2 + 3x – 5 is a quadratic

Step-by-step explanation:

A quadratic function involves the 2nd power of x:  x^2, and may (or may not) involve the 1st and zeroth power of x.

a(x) = -2x^3 is not a quadratic because of that exponent 3; in a quadratic, the highest power is always 2.

b(x) = 5x^3 + 8x^2 + 3 is not a quadratic for the same reason that a(x) is not a quadratic.

c(x) = –8x^2 + 3x – 5 is a quadratic:  the highest power of x is x^2, the other powers are x^1 and x^0.

A bird flies 61/2 mi in 20 min.
schepotkina [342]

\frac{61/2}{20} =  \frac{x}{81/8}
multiply the 2nd fraction by 8/8 to get rid of the 8 in the denominator:
\frac{61/2}{20} = \frac{8x}{81}
simplify the 1st fraction by multiplying by 2/2:
\frac{61}{40} = \frac{8x}{81}
now, you can cross-multiply: 
61*81=40*8x
4941=320x
x=\frac{4941}{320} or 15 \frac{141}{320}
