Let us first assume that the operator between 5x^3 and 3 is addition. What Louise did was incorrect, as she did not follow the proper way of expanding a binomial. The actual steps to take when taking the square of a binomial is as follows:
(5x^3 + 3)^2 = (5x^3 + 3)(5x^3 + 3)
25x^6 + 15x^3 + 15x^3 + 9
25x^6 + 30x^3 + 9
The actual answer is <span>25x^6 + 30x^3 + 9.</span>
Notice that 8 can be written in exponential form of 
When you see 
, recognize that 
3 × 
= 8
Hence, the answer is 
. Which means 256.
Here is some indices rules/formulas you might find helpful as well:
26=w-12
+12 +12
38=w
That is your answer
When you count the small lines in between 8 and 9, there are 8 lines
The difference between 8 and 9 is 1
Divide 1 by 8, you will have 0.125
This implies each small lines represent 0.125
When you count from 8 to where the point is, we have 6 small lines
Multiply the 6 by 0.125, we will have 0.75
8 + 0.75 = 8.75
The decimal is 8.75
