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.

Which is 196 written as a power of a number?<br><br> A) 98^2<br> B) 13^2<br> C) 49^4<br> D) 14^2
kap26 [50]
Its not A. because , 98^2 = 9,604
Its not B. because , 13^2 = 169
Its for sure not C. because, 49^4 = 5,764,801
It is most likey, D. because 14^2 = 196
Option: D 14^2 would most likely be your answer

Reason , because 14(14) = 196 = 14^2

Please help with step one and two.​
Nikitich [7]

Please keep in mind that the answers may not be correct. I have tried my best to answer.

1. 83.333...% would fit. We must first solve for x. As you can see, we have a similarity in the picture. 16 and 4. It's 4. So, we multiply that by 6 which equal 24=x. Now, we know that space (Not provided) is 4. So, we just divide 20 by 4. It will equal 5, add the space not provided and becomes 6. All you gotta do is now divide 100/6. 16.666... Multiply by 5 since that is how much it is providing. Then, your answer will be 83.333...%

2. 88.888...% would fit. Like the above, we must solve for x. As you can tell, the situation is similar to the original. Divide 18 by 4, 4.5. Multiply 6 by 4.5, 27. Subtract 27 by 24, 3. Now we know that the space (not provided) is 3. Divide 24" by 3, 8. Add 1 due to the non provided space. 9. Divide 9 by 100, 11.111... Multiply by 8 and get the answer. 88.888...%
