- The numeric value of this expression corresponds to the result, equal to: -39.
● To calculate this expression, we will multiply the bases of powers by the exponent values, and then add and subtract the values given in the expression. A power , is given by an , where " a " = base and " b " = exponent.
[tex] = - {3}^{2} - ( - {7})^{2} + 130°[/tex]
[tex] = ( - {3})^{2} = ( - 3) \times ( - 3) = 9[/tex]
[tex] = ( {7})^{2} = ( - 7) \times ( - 7) = 49[/tex]
[tex] = 13° = 1[/tex]
[tex] = 9 - (49) + 1[/tex]
[tex] = 9 - 49 + 1[/tex]
[tex] = - 40 + 1[/tex]
[tex] \: \boxed{-39} [/tex]
