Step 3 is wrong because when dividing exponents you subtract them x^-10 would be multiplying by x^-12 making it x^-10-12 and that would be x^-22 same applies for the y exponents

Answer:

Step 3: exponents of the same base are added during division.

Step-by-step explanation:

We have been an expression and steps used to solve the expression. We are asked to find the 1st incorrect step.

Expression: (\frac{x^{-5}y^2}{yx^3\cdot x^3y^{-5}})^2

Step 1: We will distribute the exponent as:

\frac{x^{-5\times 2}y^{2\times 2}}{y^{1\times 2}x^{3\times 2}\cdot x^{3\times 2}y^{-5\times 2}}

\frac{x^{-10}y^{4}}{y^{2}x^{6}\cdot x^{6}y^{-10}}

Step 2: Combine the exponents in denominator.

\frac{x^{-10}y^{4}}{y^{2+(-10)}x^{6+6}}

\frac{x^{-10}y^{4}}{y^{-8}x^{12}}

Step 3: Use quotient rule of exponents \frac{a^m}{a^n}=a^{m-n}.

\frac{x^{-10}y^{4}}{y^{-8}x^{12}}=x^{(-10-12)}y^{4-(-8)}

\frac{x^{-10}y^{4}}{y^{-8}x^{12}}=x^{(-22)}y^{4+8}

\frac{x^{-10}y^{4}}{y^{-8}x^{12}}=x^{(-22)}y^{12}

Therefore, the student made a mistake in 3rd step as the exponents of the same base are added during division.

In right ΔDEF, DF = 20, m∠ F = 90˚, EF = 17. Which of the following is true? Does option 5 apply
blsea [12.9K]
Doesn’t apply because tan is TOA meaning opposite/adjacent so what happens is that your numbers 17 and 20 are divided nowhere having to do with a square root

Find three consecutive even integers whose sum is −24
labwork [276]

Answer: -10,-8,-6

Step-by-step explanation:

Let be:

 x, x+2 and  x+4 the three consecutive even integers whose sum is -24

Then, we can write this expression:

 x+(x+2)+(x+4)=-24

Now, we must solve for "x":

3x+6=-24\\\\3x=-24-6\\\\3x=-30\\\\x=\frac{-30}{3}\\\\x=-10

Then you get that the others integers are:

x+2=-10+2=-8

x+4=-10+4=-6

Therefore, the  three consecutive even integers whose sum is -24 are:

-10,-8,-6

If a wage of 100% is increase by 15% what would be the new wage
IceJOKER [234]

Answer:

115%

Step-by-step explanation:

The normal wage is 100% and there was 15% increment

Which means that 100+15

It will give 115%

But in the case of having a specific value for the salary we will be able to solve further but we are not given the amount of the salary

So the final answer is 115%

I believe you understand
