Idont get these plz awnser fast and quickly keep it simple

the answer to the question would be "b"

"a" would be incorrect because you can turn it into a fraction.

"b" would be incorrect because it forms a perfect square.

"c" would also be incorrect because it forms a perfect a square. 4 x 4 = 16

the square root of what number? if you add that, then someone will probably answer the question.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
