Question

Write the expression for a number used as a factor fifteen times being multiplied by a number used as a factor ten times. Then, write the product as one power.

Answer 1

This is exponents so a number used as a factor fifteen times is X^15. Then multiplied by a number used as a factor ten times is X^10. 


The answer is: X^15 * X^10 = X^25

PS: You don't multiply exponents, you add them.

Answer 2

 x ^15    *    x^ 10 =   x ^25
