I need help with exponents. It says write the missing exponent then it gave me a problem which is 100=10. Can you help me??

The missing exponent is 2, which would be written above the 10, since 10 x 10 is equal to 100 and it would make the statement true.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
