Powers of Ten:  Raising to a Power & Extracting Roots

Raising to a power using powers of ten:

1. Raise the number to the correct power.
2. Multiply the exponents.

    Example  (2.0 x 10³)⁴  =  16 x 10¹²  =  1.6 x 10¹³ 

(Use correct scientific notation; use correct number of significant figures)

Finding roots using powers of ten:

1. If the exponent is not evenly divisible by the root, rewrite the number with a new power of ten that is evenly divisible.
2. Find the root of the number,

Divide the exponent by the root to be taken.
