What is the value of 7 to the 3rd power

Seven to the third power is
(7^3)
7 * 7 * 7
this is 
49 * 7
which is 
343

Hope this helps :)

A number "x" to the "y" power is equal to "x" multiplied by itself "y" times.

Thus, then 7 to the 3rd power is equal to 7 multiplied by itself 3 times. 

Thus: 7 x 7 x 7 = 49 x 7 = 343

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.

Ibelieve that c. recording would work best.
