You can put this solution on YOUR website!
: i cant find solution on algebra problem because of lack knowing of this problem

\n" ); document.write( "Remember when you multiply you add the exponents

\n" ); document.write( "You know that 2^3 = 8 so you have 8*8 = 64
\n" ); document.write( ":
\n" ); document.write( "They want you to get used to adding the exponents when you multiply so do this way
\n" ); document.write( "2^3 * 2^3 = 2^(3+3) = 2^6; which is 2*2*2*2*2*2 = 64
\n" ); document.write( ":
\n" ); document.write( "x^4 x
\n" ); document.write( "This is same as x^4 * x^1 = x^(4+1) = x^5
\n" ); document.write( ":
\n" ); document.write( "y^3*y^7 = y^(3+7) = y^10
\n" ); document.write( ":
\n" ); document.write( "(4^4 y^3) (-5x^5 y^2)
\n" ); document.write( "(4*4*4*4 = 256, so you have:
\n" ); document.write( "(256*y^3) * (-5x^5*y^2)
\n" ); document.write( "Multiply the numbers, add the exponents of y:
\n" ); document.write( "-1280*x^5*y^(3+2)

\n" ); document.write( "(4nx^5n) (5nx^4n)
\n" ); document.write( "I can't tell which the variable and which is exponent here
\n" ); document.write( "Assume you mean (4*n*x^(5n)) * (5*n*x^(4n)
\n" ); document.write( "20 * n^(1+1) * x^(5n+4n); add the exponents of like terms
\n" ); document.write( "20 * n^2* x^(9n)

\n" ); document.write( "The rule on exponents of exponents is you multiply the exponents
\n" ); document.write( "(2^3)^2 = 2^6
