La ayuda sería muy apreciada 16. simplify the expression. write the answer using scientific notation. (4 x 108)−2 1. 6.25 x 10−17 2. 0.0625 x 10−16 3. 6.25 x 10−18 4. −8 x 10−16

(4 x 108)−2 simplified = 430

= 4.3 × 10²(scientific notation)
= 4.3e2(scientific e notation)
= 430 × 10⁰(engineering notation)(one)
= 430(real number)

6.25 x 10−17 simplify = 45.5

= 4.55 × 10¹(scientific notation)
= 4.55e1(scientific e notation)
= 45.5 × 10⁰(engineering notation)(one)
= 45.5(real number)
0.0625 x 10−16 simplify = -15.375

= -1.5375 × 10¹(scientific notation)
= -1.5375e1(scientific e notation)
= -15.375 × 10⁰(engineering notation)(one)
= -15.375(real number)
6.25 x 10−18 simplify = 44.5

= 4.45 × 10¹(scientific notation)
= 4.45e1(scientific e notation)
= 44.5 × 10⁰(engineering notation)(one)
= 44.5(real number)
−8 x 10−16  simplify = -96

= -9.6 × 10¹
(scientific notation)
= -9.6e1(scientific e notation)
= -96 × 10⁰(engineering notation)(one)
= -96(real number)

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
