Show me how you solve it

julia-pushkina [17]

Answer:

5^20

Step-by-step explanation:

Law of Exponent I

$\displaystyle \large{ \frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n} }$

Therefore:

$\displaystyle \large{( \frac{ {5}^{8} }{ {5}^{3} } )^{4} = ({5}^{8 - 3})^{4} } \\ \displaystyle \large{( \frac{ {5}^{8} }{ {5}^{3} } )^{4} = ({5}^{5})^{4} }$

Law of Exponent II

$\displaystyle \large{( {a}^{m} ) ^{n} = {a}^{m \times n} }$

Thus:

$\displaystyle \large{( \frac{ {5}^{8} }{ {5}^{3} } )^{4} = ({5}^{8 - 3})^{4} } \\ \displaystyle \large{( \frac{ {5}^{8} }{ {5}^{3} } )^{4} = ({5}^{5})^{4} } \\ \displaystyle \large{( \frac{ {5}^{8} }{ {5}^{3} } )^{4} = {5}^{5 \times 4} } \\ \displaystyle \large{( \frac{ {5}^{8} }{ {5}^{3} } )^{4} = {5}^{20} }$

The measure of Angle E, the angle of elevation from point A to point B, is left-parenthesis 3 x plus 1 right parenthesis-degrees

Anuta_ua [19.1K]

Answer:

∠D = ∠E = 46°

Step-by-step explanation:

∠D and ∠E are interior opposite angles.

∠D = ∠E

2(x + 8) = 3x + 1

2x + 16 = 3x + 1

x = 15°

∠D = 2(15 + 8) = 2 × 23 = 46°

∠E = 3× 15+ 1 = 45 + 1 = 46°
