Question

reciprocal and exponent​

Answer 1

Step-by-step explanation:

Any number raised to the zero power (except 0) equals 1. Any number raised to the power of one equals itself. ... When a product has an exponent, each factor is raised to that power. A number with a negative exponent equals its reciprocal with a positive exponent.

Answer 2

Answer:

Step-by-step explanation:

→ A reciprocal is a pair of numbers (such as 5/6 and 6/5) that can be multiplied to produce 1.

→ The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared" Exponents are also called Powers or Indices.
