Mathematics: Pls me with these 2 math questions

I would use the starting position, sea level as zero. Then I would convert all those minutes to hours so the answer is an integer and not a decimal. 60 min * (-10 ft / 212 min) = -2.83 ft/hrround to integer = -3 ft/hr...

Mathematics

1.C. $7\sqrt[3]{x^2}$

2.D. $x^{\frac{1}{2}}$

Step-by-step explanation:

We are given that

$7(x)^{\frac{2}{3}}$

We have to write given rational exponent in radical expression

Radical expression: The expression contain square root , cube root , fourth root etc.

$7(x)^{\frac{2}{3}}=7\sqrt[3]{x^2}$

Hence, the radical expression = $7\sqrt[3]{x^2}$

Option C is true.

2. $(x^{\frac{1}{6}})^3$

We have to simplify

We know that $(a^b)^c=a^(b\cdot c}$

Apply this rule

$x^{\frac{1}{6}\times 3}=x^{\frac{1}{2}}$

$(x^{\frac{1}{6}})^3=x^{\frac{1}{2}}$

Hence, option D is true.
