You can put this solution on YOUR website!
y^4(y^7)
= y^11 {add exponents when multiplying with same base}

x^3(x^-5)
= x^-2 {add exponents when multiplying with same base}
= 1/x² {made a positive exponent by moving to the denominator}

j^a(j^b)
= j^(a + b) {add exponents when multiplying with same base}
