The expression simplified using positive exponents is 35x^4y^11.
The expression is 7x^3y^2 * 5 xy^9
In order to express it as a positive exponent, the power should be positive and not negative number and indicates how many times to multiply a base number.
Rewrite the expression to group like terms together:
(7*5) (x^3*x) (y^2*y^9)
The product rule of exponents states that when multiplying exponential expressions that have the same base, add the exponents. i.e. a^ma^n = a^(m+n)
Hence, to simplify the expression, add the exponents of x terms and y terms and multiply the constant number together.
(7*5) (x^3*x) (y^2*y^9)
35x^(3+1)y^(2+9)
35x^4y^11
