[tex] {(7 {x}^{3} {y}^{2}) }^{2} \\ = 49 {x}^{6} {y}^{4}[/tex]
2.
[tex] {(7b)}^{ - 2} \\ = \frac{1}{ {(7b)}^{2} } \\ = \frac{1}{49 {b}^{2} } [/tex]

SA SUSUNOD...
Isaalang-alang ang mga sumusunod sa pagsolve ng dalawang polynomials na may exponent:
1. Kapag may nakita kang () tapos sa labas ng parenthesis, may nakadungaw na exponent, imultiply ang exponent sa loob nito.
[tex] {(7 {x}^{3} {y}^{2}) }^{2} \\ = 49 {x}^{6} {y}^{4}[/tex]
2. Kapag nakita mong may negative ang exponent, gawing fraction ang expression.
[tex] {(7b)}^{ - 2} \\ = \frac{1}{ {(7b)}^{2} } \\ = \frac{1}{49 {b}^{2} } [/tex]
3. Kapag magmu-multiply ng dalawang terms na may exponents, i-multiply lang ang magkaparehas na terms at siyempre, i-add ang exponents.
[tex]( - 2 {w}^{7} {v}^{2} )( {w}^{2} v) \\ = - 2 {w}^{9} {v}^{3} [/tex]
4. Kapag magdi-divide ng dalawang terms na may exponents, i-divide lan ang magkatulad na terms at i-subtract ang exponents.
[tex] \frac{16 {x}^{5} {y}^{10} }{4 {x}^{2} {y}^{10} } \\ = 4 {x}^{3} [/tex]
5. Gumamit ng FOIL (First, Outer, Inner, Last) Multiplication kapag ang dalawang polynomials ay may dalawang terms.
[tex](v + 1)(2v - 2) \\ = 2 {v}^{2} - 2v + 2v - 2 \\ = 2 {v}^{2} - 2[/tex]

6. Mag-long division naman kapag isa sa kanila ay may tatlo o mahigit na terms.
[tex]( {y}^{2} - 2y - 63) \div (y - 9) \\ = y - 11 + \frac{ - 162}{ y - 9} [/tex]
