Apr 8­6:29 AM

Remember that to multiply powers with the same base, you add exponents.

Apr 8­6:30 AM

Express log64 + log69 as a single logarithm. Simplify.

To add the logarithms, multiply the numbers.

Apr 8­6:31 AM

Express as a single logarithm:  log525 + log55

Apr 8­6:33 AM

Remember that to divide powers with the same base, you subtract exponents

Apr 8­6:33 AM

Express log5100 – log54 as a single logarithm. Simplify, if possible. To subtract the logarithms, 

divide the numbers

Apr 8­6:34 AM

Express log7343 – log77 as a single logarithm. Simplify, if possible

Apr 8­6:35 AM

Because you can multiply logarithms, you can also take powers of logarithms.

Apr 8­6:35 AM

Express as a product. Simplify, if possible.

A. log2326 B. log8420

Apr 8­6:36 AM

Express as a product. Simplify, if possibly.

a. log104 b. log5253

Apr 8­6:43 AM
