Question

how much is 0.3 raised to power of 3

Answer 1

Step-by-step explanation:

3^0.3 is the same as 3^(3/10).

if you raise a number to a fractional power, then you are:

raising it to the power of the numerator

finding the root that the denominator shows.

e.g. a^(1/2) is the square root of a, since a^1 is a, and the 2nd root of a is the square root.

to find 3^(3/10), you need to:

raise 3 to the 3rd power (i.e. cube it)

find the 10th root of the result.

3^3 = 27.

the 10th root of 27 is 1.39038917032.., or 1.39 to 3 significant figures.
