Question

1. Determine as potências.
a) 516' =

b) 40190 =
g) -104 =
c) 1 20 =
h) -(-7)3 =
i)

d) 0676 =
4
e) 107 =​

Answer 1

$\large{a)516 {}^{1} } = \boxed {\red{516}}$

______________________________________

$\large {b)4019 {}^{0} } = \boxed{ \red{ \: 1 \: }}$

______________________________________

$\large{c)1 {}^{20} } = \boxed { \red{ \: 1 \: }}$

______________________________________

$\large{d)0 {}^{676} = \boxed{\red{ \: 0 \: }}}$

______________________________________

$\large{e)10 {}^{7} } =$

$10 \times 10 \times 10 \times 10 \times 10 \times 10 \times 10 =$

$\large\boxed{ \red{10 \: 000 \: 000}}$

______________________________________

$\large{f)( - \frac{2}{9} ) {}^{3} } =$

$\large{ - ( \frac{2}{9} ) {}^{3} } =$

$\large{ \frac{2 {}^{3} }{9 {}^{3} } } =$

$\large\boxed{ \red{ \frac{8}{729} }}$

______________________________________

$\large{g) - 10 {}^{4} } =$

$\large{ - (10 \times 10 \times 10 \times 10)} =$

$\large\boxed{ \red{ - 10 \: 000}}$

______________________________________

$\large{h) - ( - 7) {}^{3} } =$

$\large{( - 7) {}^{3}} =$

$\large{ - (7 \times 7 \times 7)} =$

$\large\boxed{ \red{ - 343}}$

______________________________________

$\large{i)( - \frac{1}{4} ) {}^{2} } =$

$\large{( \frac{1}{4} ) {}^{2} } =$

$\large{ \frac{1 {}^{2} }{4 {}^{2} } } =$

$\large\boxed{ \red{ \frac{1}{16} }}$
