Express the following in exponential notation:<br> (-13) X (-13).<br> 35 times
miv72 [106K]

Answer:

(-13) * (-13) = (-13)^{2}

35 * 35 = 35^{2}

Step-by-step explanation:

Given

(-13) * (-13)

Required

Express as an exponential notation

(-13) * (-13)

Apply the following law of indices

x^a * x^b = x^{a+b}

This gives:

(-13) * (-13) = (-13)^{1+1}

(-13) * (-13) = (-13)^{2}

<em>The second complete is incomplete; However, I'll assume it is: 35 times 35</em>

35 * 35

Using the same law applied in (1) above:

35 * 35 = 35^{1+1}

35 * 35 = 35^{2}

On a trip to Griffith Observatory, Dave rode his bicycle six more than twice as many miles in the afternoon as in the morning. I
podryga [215]

Answer:

Dave rode his bicycle 17 miles in the morning

Dave rode his bicycle 40 miles in the afternoon

Step-by-step explanation:

* Lets study the information to solve the question

- Dave rod his bicycle in the morning and again in the afternoon

- Six more than twice as many miles in the afternoon as in the morning

  means the distance in the afternoon is 6 more than twice the distance

  in the morning

- The entire trip was 57 miles means the total distance in the morning

  and in the afternoon was 75

* To solve the question let the distance in the morning is x miles

∵ The distance in the morning = x miles

∵ The distance in the afternoon is 6 more than twice the distance

  in the morning

∴ The distance in the afternoon = 2x + 6 miles

∵ The distance in entire trip = 57 miles

- The distance in the morning and the distance in the afternoon = 57 miles

∴ x + (2x + 6) = 57 ⇒ simplify

∴ 3x + 6 = 57 ⇒ subtract 6 from both sides

∴ 3x = 51 ⇒ divide both sides by 3

∴ x = 17 miles

∵ The distance in the morning is x miles

∴ Dave rode his bicycle 17 miles in the morning

∵ The distance in the afternoon = 2x + 6 miles

- Substitute the value of x

∴ The distance in the afternoon = 2(17) + 6 = 34 + 6 = 40 miles

∴ Dave rode his bicycle 40 miles in the afternoon
