It could be written as 3^3*5^3.
Anything to the third power: 5^3 = 5 x 5 x 5 = 125
It is 15^3 is exponential notation,3000 + 200 + 70 + 5 in expanded notation and 3.375^10^3 in standard form.
The exponential notation of 0.00001 is 1.0 × 10-5
5 cubed = 5 x 5 x 5 = 53
It means in powers as for example 5*5*5 in exponential notation is 5^3 which means 5 to the power of 3
It is 5, exactly as in the question.
6.75511e+5
21^5!
An exponential or power term.
262,144 = 2.621440e+5
100,000 = 1e+5
