Answer 2

Answer:

Option (d)

The exponential form of 4× 4×4×4x4....... 4 (20 times) = $4^{20}$

Step-by-step explanation:

4×4×4×4× 4× 4×4×4× 4×4×........4(20 times) = $4^{20}$ = 4^20

Exponential form: The exponential form is an easier way of writing repeated multiplication involving base and exponents. That is the way of representing repeated multiplications of the same number by writing the number as a base with the number of repeats written as a small number to its upper right.

e.g. 5 x 5 x 5 = 5³

5 is called base.

The small number 3 is called an exponent, index, power, or order.
