Question

25 = 5² in log form is ______.

Options

• log₅ 25 = 2

• log₂ 5 = 25

• log₅ 2 = 25

• log₂ 25 = 5

Answer 1

25 = 5² in log form is log₅ 25 = 2.

Explanation:

25 = 5²

We need to express this in logarithmic form.

The general form of a logarithmic expression is:

log_b a = c if and only if b^c = a

For 25 = 5², the logarithmic form is:

log₅ 25 = 2
