To make a negative, just hit the - symbol....for example (-1)
$${{\mathtt{8}}}^{{\mathtt{2.666\: \!666\: \!666\: \!666\: \!666\: \!7}}} = {\mathtt{256}}$$
Hey yall! Let's make 300!
Exactly what Geno said, it can't be a decimal or fraction!!!
29/197 is the fraction
$$\left({\mathtt{7}}{\mathtt{\,\times\,}}-{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}-{\mathtt{5}}\right) = {\mathtt{280}}$$
Sure thing!!!!
Yep!
$${\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{317\,000\,000\,000}} = {\mathtt{1\,268\,000\,000\,000}}$$
Did I help you?
