Which expression is equivalent to (m^8n^−4)^14 ?
umka2103 [35]

Which expression is equivalent to (m^8\times n^-4)^ 1/4

Answer:

m^2/n

Step-by-step explanation:

Given.

I assume this is your expression:

The expression is =(m^{8} \times n^{-4} )^{\frac{1}{4} }

Now simplify the expression by multiplying the power.

=(m^{8\times \frac{1}{4}} \times n^{-4\times \frac{1}{4}}} )

=(m^{2} \times n^{-1} )

=\frac{m^{2}}{n}

So, the expression is equivalent to \frac{m^{2}}{n}

2+3/4x=5/12<br> Rewrite the equation so that it does not have any fractions
Viktor [21]

Answer:

24+9x=5

Step-by-step explanation:

First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.

2*12=24,

3/4*12=36/4=9,

5/12*12=60/12=5.

Using these values will give your final equation: 24+9x=5

The diagonals of a rectangle ABCD meet at O if AO=(2x+3)cm and DO=(5x)cm find the length of its diagonals also find the perimete
vfiekz [6]

Step-by-step explanation:

AO = DO

2x+3 = 5x

3 = 5x-2x

3 = 3x

x = 1

DO = 5(1)=5cm

AC = 2×5 = 10cm

BC =√10²-8²

= √100-64

=√36

=6 cm

therefore, the perimeter of the rectangle

= 2×(8+6) = 2(14) = 28 cm
