Answer:
In multiplication of algebraic expression before taking up the product of algebraic expressions, let us look at two simple rules.
(i) The product of two factors with like signs is positive, and the product of two factors with unlike signs is negative.
(ii) if x is a variable and m, n are positive integers, then
(xᵐ × xⁿ) = xm+n
Thus, (x³ × x⁵) = x⁸, (x⁶ + x⁴) = x6+4 = x10, etc.
