MTAP Reviewer for Grade 9

This reviewer was taken from 2013 Metrobank-MTAP-Dep-Ed Math Challenge for third year. This is also advisable for fourth year and second year.

Directions: Give all fractions in the lowest terms. Eliminate negative exponents and rationalize denominators. Give equation of the lines in slope-intercept form.

4. Simplify: 6mn^4\root 3\of{8m^{11}n^4}-2m^3n\root 3\of{m^5n^{13}}

5. Simplify: xy^2\sqrt{16x^3y^5}-7y\sqrt{x^5y^7}+4y^3\sqrt{4x^5y^3} ifx>0 and y>0.
