Question

sabendo que A= 2^-4 e B= 4^-2 qual é o valor de A+B e A e B​

Answer 1

$a = 2 {}^{ - 4} = \frac{1}{2 {}^{4} } ={ \large\red{ \frac{1}{16} }}$

$b = 4 {}^{ - 2} = \frac{1}{4 {}^{2} } = {\large \red{\frac{1}{16} }}$

______________________________________

A + B

$\frac{1}{16} + \frac{1}{16} =$

$\frac{1 + 1}{16} =$

$\frac{2}{16} =$

$\frac{2 \div 2}{16 \div 2} =$

$\large \boxed{\red{ \: \frac{1}{8} \: }}$

____________________________________

A ÷ B

$\frac{1}{16} \div \frac{1}{16} =$

$\frac{1}{1} =$

$\large\boxed{ \: \red{1} \: }$
