Logarithms Solving

We want to solve for x. Which of these is the correct "step 1"?

Continue solving for x. Which is the correct "step 2"?

Finish solving for x.

Fill in the blank in the box below

log₉(5x + 21) = log₉(2x + 9)

• 9

• -4

• 7

• -10

log_x(121) = 2

• x = 10

• x = 11

• x = 242

• x = 12

log₉(x) = 3

• x = 27

• x = 79

• x = 729

• x = 19,683

Write in logarithmic form:
9² = 81

• log ₉ 81 = 2

• log ₂ 81 = 9

• log ₉ 2 = 81

• log ₂ 9 = 81

Write in logarithmic form:
4⁵ = 1024

• log ₄ 1024 = 5

• log ₅ 1024 = 4

• log ₄ 5 = 1024

• log ₅ 4 = 1024

Write in logarithmic form.
5² = 25

• log₅2 = 25

• log₂25 = 5

• log₂₅5 = 2

• log₅25 = 2

To evaluate a logarithm statement log₉81, you think "9 to what power is 81".

• True, and it's 2

• False
