1.Simplify 5 to the 5th over 5 to the 8th.
timurjin [86]
Q1. The answer is <span>1 over 5 to the 3rd power.

</span>5 to the 5th is 5⁵
5 to the 8th is 5⁸
5 to the 5th over 5 to the 8th is \frac{ 5^{5} }{ 5^{8} }
To simplify, we will use two rules: 
\frac{ x^{a}}{ x^{b} } = x^{a-b} \\ x^{-a} = \frac{1}{ x^{a}}
Therefore:
\frac{ 5^{5} }{ 5^{8} } = 5^{5-8} =5^{-3}= \frac{1}{5^{3}}
\frac{1}{5^{3}} is the same as 1 over 5 to the 3rd power.


Q2. The answer is <span>(53)−4.

The exponents are multiplied when are expressed in the form:
</span>(x^{a}) ^{b}= x^{a*b}
So, (5^{3} )^{-4}=5^{3*(-4)}=5^{-12}

Other choices are incorrect:
<span>one third to the 4th times one third to the 7th is </span>( \frac{1}{3} )^{4} *( \frac{1}{3} )^{7}=( \frac{1}{3} )^{4+7}
3 to the 7th over 3 to the 15th is \frac{ 3^{7} }{3^{15}} =3^{7-15}
<span>45 ⋅ 42 is </span>4^{5}* 4^{2} =  4^{5+2}

A. Find and explain the error in the work shown.
Marizza181 [45]

<u>The error is that they had placed the numbers in the wrong placeholder.</u> Remember that the Distance formula is D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} .

<em><u>Correct Work:</u></em>

D=\sqrt{(5-(-1))^2+(16-15)^2}\\D=\sqrt{6^2+1^2}\\D=\sqrt{36+1}\\D=\sqrt{37}\ \approx 6.08

Find the value of x.
agasfer [191]

Answer:

\boxed {\boxed {\sf A. \ 18}}

Step-by-step explanation:

The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.

Therefore, the sum of the angle measures must equal 90. We can set up an equation.

56+(x+16)=90

Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.

(56+16)+x=90\\

72+x=90

Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.

72-72+x=90-72

x=18

x is equal to 18 and choice A is correct.
