M – 4.7) = 3.5 = 1<br> what value of m makes the equation true
GREYUIT [131]

The value of m which makes the equation true is; 8.2

<h3>How to solve one variable equations</h3>

The given equation is;

  • m – 4.7 = 3.5

The value of m, for which the equation is true can be evaluated as follows;

m – 4.7 = 3.5

Add 4.7 to both sides of the equation to isolate m.

m - 4.7 + 4.7 = 3.5 + 4.7

m = 8.2

A one variable equation also known as linear equation is an equation in which one unknown variable is solved for.

Therefore, the value of m which makes the equation true is; 8.2

Match each complex number with its equivalent expression i^157 i^315 i^102 i^76
ryzh [129]

Answers:

i^{157} = i\\\\i^{315} = -i\\\\i^{102} = -1\\\\i^{76} = 1\\\\

=====================================================

Explanation:

By definition, i = \sqrt{-1}

Squaring both sides gets us i^2 = -1

Then multiply both sides by i to get i^3 = -i

Repeat the last step and you should get i^4 = -i^2 = -(-1) = 1

---------------

Notice we have this pattern going on:

i^0 = 1\\\\i^1 = i\\\\i^2 = -1\\\\i^3 = -i\\\\i^4 = 1\\\\

Once we reach i^4, we start the process over again.

It repeats every 4 terms.

This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.

157/4 = 39 remainder 1

That remainder 1 is the exponent of the simplified term

i^{157} = i^1 = i

---------------

Similarly,

315/4 = 78 remainder 3

So i^{315} = i^3 = -i

---------------

102/4 = 25 remainder 2

i^{102} = i^2 = -1

----------------

76/4 = 19 remainder 0

i^{76} = i^0 = 1
