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}

What’s the answer pleazzzzz helplllllll 9m^2-4m-6 by 3m
dlinn [17]

Answer

D. 3m - 4/3 -2/m


<u>Explanation</u>

(9m²-4m-6) ÷ 3m  = 9m²/3m - 4m/3m - 6/3m

Carry out the division, each term is divided by 3m.

9m²/3m = 3m

- 4m/3m = -4/3

- 6/3m = - 2/m

Finally you will get,

<em>3m - 4/3 -2/m</em>
