Which sum will be irrational? (1 point)

Question

3 + 2
start root 19 end root plus start fraction 7 over 2 end fraction
Start Fraction 18 over 3 End Fraction plus Start Fraction 11 over ten thousand End Fraction.
–6 + (–3.251)

Which product will be rational? (1 point)
17 point Modifying Above 12 with bar times 33
start root 3 end root times start root 9 end root
4 times pi
negative start root 20 end root times 15

A whole number is added to a number with two digits after the decimal point. To make sure the answer is reasonable, how many digits should the sum have after the decimal point?
none
1
2
infinitely many

Answer 1

1.D
2.B
3.B

Answer 2

#1 (B) since 19 is not a perfect square, √19 is irrational. 18/3 is just 6, and 11/10000 is just a rational number.

#2 (A)
any repeating decimal is rational.

#3 (B) ok.

I can't say I like your syntax. Even if you can't figure out how to copy/paste special symbols, it would be much better to say things like

sqrt(19) + 7/2
18/3

* for multiply
/ for divide
^ for powers: x^2 means x squared
sqrt(x) for square root

And use parentheses to make sure:

2/3+7 is not the same as 2/(3+7)

multiply and divide are to be done before add and subtract, unless parens dictate otherwise.
