Answer:
In this maths tutorial, we introduce exponents / powers and roots using formulas, solved examples and practice questions.
Powers and Roots | Formulas, Solved Examples, Practice Problems
Exponents, also called powers, are a way of expressing a number multiplied by itself by a certain number of times.
When we write a number a, it is actually a1, said as a to the power 1.
a2 = a*a
a3 = a*a*a
:
:
an = a*a*a*a* . . . n times.
Basic formulas in Powers and Roots
Some basic formulas used to solve questions on exponents are:
(am)n = (an)m = amn
am.an = am+n
a-m = 1/am
am/an = am-n = 1/an-m
(ab)n = anbn
(a/b)n = an/bn
a0 = 1

============================================================
Work Shown:

The geometric mean of two numbers has us do two steps in this order
- Multiply the values
- Apply the square root
The geometric mean can be applied to more than two values. Regardless of how many values you have, you always multiply them out. However, the number of values will tell you what kind of root you'll take (eg: 3 values leads to a cube root; 4 values means you'll take a fourth root, etc).
The answer is D neither because its
