Question

Simplify the expression

Answer 1

Here we use a law of exponent i.e.

`{a}^(m) * {a}^(n) = {a}^(m + n) \\ \\`

So,

5² × 5³ × 5²

`= {5}^(2 + 3 + 2) \\ \\ = {5}^(7) \\ \\ = 78125 \\ \\`

Therefore the answer is 78125 or simply 5⁷

Hope it helps you :)

Answer 2

2500

Explanation:

5×5 ( 5×5×5 - 5×2 )

25 ( 125 - 25 )

25 ( 100)

25 × 100

= 2500
