Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 =
.
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
![[\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}](https://tex.z-dn.net/?f=%5B%5Csqrt%5B5%5D%7B%28-21%29%7D%5D%5E6%20%20%3D%20%28-21%29%5E%5Cfrac%7B6%7D%7B5%7D)
Step-by-step explanation:
1 hour she travels = 19 km
60 min = 1 hr
53 min = 1/60 * 53 hr = 53/60 hr
Now,
1 hr = 19 km
4 + 53/60 hrs = 19 * ( 4 + 53/60) km
She travels 92.78 km in 4 hrs and 53 minutes.
