You can put this solution on YOUR website! If the x's are multiplication symbols (I'm assuming there are only y's as variables) when multiplying variables with exponents you add the exponents. When multiplying numbers with exponents, add the exponents. Remember with y alone there's an exponent of 1 There's your answer.
You can put this solution on YOUR website! y^3 means y*y*y; the 3 indicates you have 3 Y's to multiply
So y^3*y^3*y means you have 3 y's then 3 more y's then 1 y
That makes 7 y^2 to multiply or y^7
-------
So y^3*y^3*y=y^7
Notice you can find the exponent of the answer by adding the exponents
of the factors: 3 + 3 + 1 = 7
