Which student evaluated the power correctly?

Aida's work - 5^4=5x5x5x5=625

Hector's work-5^4=5x4=20

Camila's work-5^4=5+5+5+5=20

Juan's work-5^4=5x5x5=25

Step by step equation

Aida is correct.

Step-by-step explanation:

A exponent that is a whole number greater than 1 means the number of times you write the base and use it in multiplication.

The base is 5. The exponent is 4.

That means write the base 4 times.

5 5 5 5

The operation between the bases is multiplication.

5 * 5 * 5 * 5

Now just multiply two numbers at a time from left to right until you do all the multiplications.

5 * 5 * 5 * 5 =

= 25 * 5 * 5

= 125 * 5

= 625

5^4 = 5 * 5 * 5 * 5 = 625

Aida is correct.
