Conner and Jana are multiplying (3⁵6⁸)(3⁹6¹⁰).

ad-work [718]

<h3>Conner work is correct. Jana work is wrong</h3>

<em><u>Solution:</u></em>

<em><u>Given that,</u></em>

<em><u>Conner and Jana are multiplying:</u></em>

$(3^56^8)(3^96^{10})$

Given Conner's work is:

$(3^56^8)(3^96^{10}) = 3^{5+9}6^{8+10} = 3^{14}6^{18}$

We have to check if this work is correct

Yes, Conner work is correct

From given,

$(3^56^8)(3^96^{10})\\\\3^5 \times 6^8 \times 3^9 \times 6^{10}$

Use the following law of exponent

$a^m \times a^n = a^{m+n}$

Therefore,

$3^5 \times 6^8 \times 3^9 \times 6^{10} = 3^5 \times 3^9 \times 6^8 \times 6^{10} = 3^{5+9} \times 6^{8+10} = 3^{14} \times 6^{18}$

<em><u>Given Jana's work is:</u></em>

$(3^56^8)(3^96^{10}) = 3^{5.9}6^{8.10} = 3^{45}6^{80}$

This is incorrect

The powers of same base has to be added. But here, powers are multiplied which is wrong

Find the area of a trapezoid with base lengths 3 and 5 and heigh of 9

Likurg_2 [28]

A <u>trapezoid</u> is a quadrilateral with exactly one pair of parallel sides.

Formula for area: $A = \frac{1}{2}(^{b}1 + ^{b}2)(h)$

In this formula, the bases are the parallel sides.

Now plug the information into the formula.

$A = \frac{1}{2} (3 + 5)(9)$ .

Follow your order of operations, simplify inside the parentheses first.

$A = \frac{1}{2}(8)(9)$ .

(1/2)(8) is 4 so we have (4)(9) which is 36.

So the area of the trapezoid is 36.
