Which expression represents (−21−−−−√5)6 in rational exponent form? (−21)6/5 −215/6 (65)−21 (56)−21

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.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
