Use an exponent when a number or term is multiplied by itself multiple times.

Let's use parentheses to show this, by separating like numbers/terms.

2x2x5x5x7x7x7
(2x2) x (5x5) x (7x7x7)

Now, exponents are witten as n^x (use superscript when writing), where n is the number being multiplied, and x is the number of times it is multiplied by itself.

2x2 becomes 2^2
5x5 becomes 5^2
7x7x7 becomes 7^3

and so you write it as 2^2 * 5^2 * 7^3.

2^2 * 5^2 * 7^3

basically it reads:

2 squared times 5 squared times 7 cubed
OR
2 to the power of 2 times 5 to the power of 2 times 7 to the power of 3

The amount of same numbers should tell you what power you should raise the number to. For example, if you had 3*3*3*3, you would raise 3 to the power of 4, since there are four 3's.

When you multiply one number to itself, you can write:
a*a = a^2
a*a*a = a^3
a*a*a*a = a^4
.....
and so on

In you case...
2*2 = 2^2
5*5 = 5^2
7*7*7 = 7^3

And you can write
2^2 + 5^2 + 7^3
