What is the correct expression of 34,000 x 96,000 using scientific notation?

For this case we have the following product:

We can rewrite both numbers using scientific notation.

We have then:

Then, we can rewrite the expression as follows:

Same basis, the exponents are added:

Multiplying the expression within the parenthesis we have:

Rewriting the left term as scientific notation we have:

Finally we have:

the correct expression of 34,000 x 96,000 using scientific notation is:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
