Given the numerical expression:
(13)^2(13)^-4(13)^5
Determine the final degree of 13
Solution:
In order to determine the final answer, we apply the rules of exponents, which involve multiplication between two or more numbers.
(a^n)(b^n) = n+n
it states that whenever a number with a degree is multiplied to another number with a degree, we add their degrees/exponent together.
(13)^2(13)^-4(13)^5
The exponents of the each number are as follows; 2, - 4, 5
Now we need to add them all together.
= 2, -4 , 5
= 3
(13)^3
Final Answer:
13^3
