How do you write 7 × 7 ×7 ×7 ×7 in exponential form?

##7^5##

A short hand method of writing repeated multiplication of a number is to express it in ##color(blue)"exponent form"##

For example.

##2xx2 = 2^2" the "color(blue)(2) " in " color(blue)(2)^2" is called the base and the " 2" in the"2^color(red)(2)" the exponent"##

also ##2xx2xx2xx2=2^4" and so on"##

##rArr=7xx7xx7xx7xx7=7^5" in exponential form"##

The base is the value of the number being multiplied, in this case 7

and the exponent is the number of times, the number is being multiplied. In this case 5.
