Answer:
90
Step-by-step explanation:
We'll calculate these squares one by one, then add them together. First, let's work on [tex]1^{2}[/tex]. This is equivalent to 1 times itself two times, which is equal to 1, since 1 times 1 is 1.
Now, we'll look at [tex]2^{3}[/tex]. This is equal to 2 times 2 times 2, which is equal to 8. 2 times 2 is 4, times 2 is 8.
Finally, let's look at [tex]3^{4}[/tex]. This is equal to 3 times 3 times 3 times 3 - 3 times 3 is 9, times 3 is 27, times 3 is 81. So that's our last number.
What's 1 + 8 + 81? 1 + 8 is 9, and 81 + 9 is equal to 90. So that's the sum of the expression.
Hopefully that was helpful! If you have further questions, let me know.
