The answer for the exponential expressions 1,2,3 and 4 will be 4.5,\frac{1}{2},2,1 respectively.

<h3>What exactly is an exponent?</h3>

Exponential notation is a type of mathematical shorthand that allows us to write complex formulas in a more concise manner.

The basis of an exponent is a number or letter. It means that the base will be raised to a given level of power. The base is X, and the power is n.

The properties of the exponent used;

\rm m^a \times m^b = m^{a+b} \\\\ m^a \times n^a = {mn}^a \\\\ m^a \times m^b = m^{a-b} \\\\ m^0 = 1

Expression 1;

\frac{(2.3^{-2})^2(5.3^2.2)^2}{(3)^-2(5.2)^2} \\\\ \frac{2^3.3^{-6}.5^2.3^6}{3^{-2}.5^2.2^2} \\\\ 4.5

Expression 2;

(3^3)(4^0)(3.2)^{-3}(2)^2 \\\\ 3^3.1.3^{-3}.2^{-3}.2^2 \\\\ \frac{1}{2}

Expression 3;

\frac{(3^7.4^7)(2.5)^{-3}(5)^2}{12^7.5^{-1}.2^{-4}} \\\\ \frac{3^7.4^7.25^{-3}.5^{-3}.5^2}{12^7.5^{-1}2^{-4}} \\\\ 2

Expression 4;

\frac{(2.3)^{-1}.2^0}{(2.3)^{-1}}\\\\ \frac{2^{-1}.3^{-1}.1}{2.3}\\\\ 1

Hence, the answer for the exponential expressions 1,2,3, and 4 will be 4.5,\frac{1}{2},2,1 respectively.

I assume you are being asked to solve these equations.  Since there wasn't an explanation as to how you are expected to solve them, I chose to demonstrate how to use a calculator matrix function. You can find matrix calculators online.  My instructions are for a TI-84
Push the blue 2nd button then push x^-1 button (it says matrix above this button in blue)
Arrow over to edit to change the dimensions of the matrix and to put in your values.  You have 3 equations (3 rows) and 4 terms (4 columns) so you put a 3x4 in for the dimension and the coefficients (see images).
You use the rref option in the math column in matrix to calculate the answer. 
The numbers at the end are the solutions. x = -4, y = 2, z = -1

2x=13+7

2x=20

x=20/2

x=10

b)3x+4=25

Nonamiya [84]

Answer:

sqrt(29)

Step-by-step explanation:

To find the distance between two points, we use the formula

d = sqrt( ( x2-x1)^2 + (y2-y1)^2 )

d= sqrt( ( 8-6) ^2 + ( 2-7)^2)

  = sqrt ( 2^2 + (-5)^2)

  = sqrt 4+25)

  = sqrt (29)
