todd = 8 + 9

sally = 18 + 7

Just keep adding until they have the same amount if they ever do.

todd 17 26 35 44 53

sally 25 32 39 46 53


so it took them  5 mouths and they both have 53  CD's

Which expression is equivalent to i 233?<br> a)1<br> b)–1<br> c)i<br> d)–i
Aneli [31]

We have to find the value of the expression i^{233}

We know that the below values.

i^2=-1\\i^4=1

Hence, in order to find the value of the given expression, we can first rewrite it in terms of i^4

i^{233}=(i^4)^{58}\cdot i

Now, we know that i^4=1

Hence, we have

i^{233}=(1)^{58}\cdot i

i^{233}=1\cdot i

i^{233}=i

C is the correct option.
