Question

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

Answer 1

`7xx7xx7xx7xx7 = 7^5`

Explanation:

An exponent is the same as an index and tells us what a power is made up of.

`7xx7xx7xx7xx7 = 7^5`

The powers of 7 are: 7; 49; 343; 2,401; 16,807.

They are written with exponents as:

`7^1; 7^2; 7^3, 7^4, 7^5`

Answer 2

`7^5`

Explanation:

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.
