Question

Calcule as potências a seguir e escreva a resposta respectivamente 8 elevado a 2; 10 elevado a menos dois;- 4 elevado a 4; abre parentes - 6 fecha parentes elevado a 4

Answer 1

We just have to solve each power.

`8^(2) = 8 * 8 = 64\\10^(-2) =(1)/(10^(2) ) =(1)/(100)=0.01 \\(-4)^(4)=(-4) * (-4) * (-4) * (-4)=256 \\(-6)^(4)=(-6) * (-6) * (-6) * (-6)=1,296`

Remember, to solve a power, we just need to multiply its base as many times indicates its exponent.

It's important to know that the negative exponent indicates a position, that's why in the second exercise we needed to change the position of the power to continue.
